Do not repeat the experiments shown in this video!
So, today I will tell you about the metal that can replace gold, about niobium.
In the periodic table of chemical elements, niobium is placed in the 5th group, between vanadium and tantalum.
It got its name in the honor of Niobe, the daughter of the ancient Greek king Tantalus, and this is not a coincidence, because the properties of niobium and tantalum are very similar and at first sight they are quite hard to distinguish.
Niobium is mined from the mineral columbite, where tantalum is also present.
Because of that, until 1949 in the US, niobium was also called columbium, as in the 19th century, American scientists sometimes considered tantalum and niobium the same element and did not think about new names.
Now, when obtaining niobium from ore, it is purified from tantalum and other metals, and so pure niobium pentoxide is acquired, which is then subsequently dissolved with hydrofluoric acid, thereby obtaining complex niobium compounds.
Which are then reduced by the metallic sodium to a metallic state.
After such a process, what is obtained is a high-purity niobium which in its appearance resembles a white and a malleable metal.
If you compare its appearance with tantalum, then you can immediately see the difference in that tantalum has a more shiny surface, though it might be just the way they produce these rods.
Also niobium is about 3 times cheaper than tantalum.
Due to its high plasticity, it is easy to make a niobium foil, which is much harder to distinguish from the foil of tantalum.
Although, there is one way, as the density of niobium is almost 2 times less than that of tantalum, therefore these metals can be easily distinguished by means of scales. - Věda a technologie
As a physicist working on quantum computing, I loved that you mentioned the use of niobium in superconducting qubits. Not many people outside of the field know about that!
I would have though that you were a business owner, perhaps owning a dimadome of some sort, maybe in dimsdale.
I work as a toilet cleaner! I love that you didnt mention anything about it. Many people in my field couldnt care less about if you are a physicist or whether you love cats !
Niobium is almost a miracle element, it increases the heat stability of super alloys and as little as 0.02% Niobium increases the structural strength of steel quite dramatically.
It also has amazing superconductive and magnetic properties.
Man it's becomes superconductive at 263 degree Celsius. What good superconductor
Definitely one of the best science channels on CZcams. Instead of just reading from Wikipedia and recording his face, he uses his own footage from his own experiments.
Something_to_appease_Google check out Cody's Lab
Moonfire also an excellent channel
And very high quality as well.
No comparison. Perfect subtitles and all the chemical details. Watch nurdrage instead of cody'slab.
NileRed is very good as well
"phosphate free" tri sodium phosphate

google TSP-PF MSDS for the safety datasheet. It is a phosphate free preparation with a - supposedly - similar cleaning effect as the orginal TSP product
@@goamarty
Yeah it's worse at cleaning but it doesn't contain phosphate.
@@goamarty I love how one of the surest sources of civil commentary on the internet is in practical science YT pages.
TSP kicks ass, esp mixed with NaOH
@@mattlogue1300 Why are you mixing those two?
I'm at the end of my 4 year chemistry degree and this video has been more mind blowing than anything I learnt.
Wow yay
I love this series.
Uriah #METOO This was one of the more amazing metals and presentation. Bravo Thoisoi !
I love this accent
Who are you?
Uriah Siner o hi again
Can you make one about the king of all metals plutonium??
That was absolutely fascinating, and your color producing experiments were creative and yielded beautiful results. Thanks
Beautiful! Loved the clip showing the sparks going across the metal.
I really LOVE your videos! This one was really fascinating. Thank you!
You can read any scientific article...
1) you can go to a university and ask to retrieve the article through their subscription, they usually have one internally
2) you can use secondary publishing routes where the article might be found, such as arXiv, citeseerX and researcher's homepage
3) you can mail the original researchers and ask for it - if they performed the work on public funding, then it's in public domain, and they have no reason to refuse you
4) if all else fails, there's sci-hub
I'm a bit miffed about the clickbaity title though. Main use of gold is technical, where its inertness is of particular value, that it's soft and will not oxidise. But if niobium oxidises, then it's not a viable replacement.
just google: reddit sci hub for active links (note, never do this, this is for educational purposes only ;)
The EU just (2018) released a directive that all scientific articles must be available to the public free of charge.

They also just passed Article 13.
This is probably my favorite video on this channel so far. Great stuff!
Fantastic video, one of your very best. I'm glad to be one of your supporters on Patreon.
Cool video! I really like what you made, what beautiful colors! I have some nice piercing jewelry made from niobium, some anodized in colors, some charcoal. I prefer it over stainless steel, but it doesn't hold a thread well, so you can't screw two pieces together.
Wow, fantastic work!
This is the most beautiful and informative and creatively inspiring video I have seen in a very long time!! Thank you so much for making giving his little gift! A packet of light! Keep it up!
Thanks for this, I enjoyed this video of yours the most so far!
I could watch whole video of you roasting the google search :D
year 216
Brilliant nerd work! Love it! Keep it up!
Great experiments, really enjoy this video, thanks for sharing
Very informative and good use of practical experiments. This is a great series to watch when you got nothing to do but what to learn something!
Tantalum has been used for falsifying gold, it's so dense. You take tantalum and maybe a bit of platinum in the right proportions to get the same density as gold, and then gold plate the whole thing, though it would be far easier to use tungsten since it is almost the same density as gold already and you would need very little platinum. This is what you can expect to get if you buy gold bullion from China btw.
I love your informative videos. Thank you sir!
Excellent technical presentation. I used to work A LOT with Niobium and Tantalum in the specialty bronze industries.
The spark is crazy!!
Nice work!!!
When art and science collide, beautiful reactions occur, great video!
Andres Covarrubias Art, Science and Memes..!
Great video!
Very cool experiment. I wonder if the cost of processing and making this metal would be worth it or just as costly as real gold once it's all said and done. Not by the value of the metal but just purely for the cost that goes into the refining and production process. Would be interesting to see the comparison.
Niobium, or columbium, is a chemical element with the chemical symbol Nb (formerly Cb) and atomic number 41.
Niobium is a light grey, crystalline, and ductile transition metal.
Pure niobium has a Mohs hardness rating similar to pure titanium, and it has similar ductility to iron.
Niobium oxidizes in Earth's atmosphere very slowly, hence its application in jewelry as a hypoallergenic alternative to nickel.
Niobium is often found in the minerals pyrochlore and columbite, hence the former name "columbium".
Its name comes from Greek mythology: Niobe, daughter of Tantalus, the namesake of tantalum.
The name reflects the great similarity between the two elements in their physical and chemical properties, which makes them difficult to distinguish.
tholsoi, you deserve way more likes and way more subscribers:) nice camera, nice quality , and very well explained:) keep up the good work:)
“Commerce in all its glory”
As many countries have learned through painful lessons and great human suffering, it's by far the least bad method of ensuring that people get what they need.
Besides being baked deeply into our DNA.
You're good bro... I wish I had a Chemistry Teacher like you.
Subscribe--watch--learn.
Wish granted! This genie stuff is easy.
I love your approach to science because anyone can lookup a documentary about anything and be wowed! But with your videos, it feels like we're all discovering for the first time together! And then you give fun facts, like what it's used for, etc! Great job!!! Keep going bc I just subscribed!!! 😍😍😍
I like science
Another great episode, thank you Thoisoi!👍
your kitty is adorable, great videos bro
Very good
I love this series, pls keep on making more videos about each chemicals in the periodic table, and im hoping for more crystal growing videos, maybe an another color???
subscribed..... great info !!!! Thank You !
beautiful metal art !
lmao I got a notification on this video that “some users found this content to be offensive” perhaps science has become a topic of offense nowadays to the younger, easily offended generation. Keep up the great vids👍
Brazilian leftists are finding it offensive lol
@@LaserShowsManaus Kind of like how right wingers deny the theory of evolution and think the world is 3k years old?😂
Reported.
@@ButterBallTheOpossum okay, why do you think that is only applicable to right wingers? Thats simply a lie
@@ButterBallTheOpossum yea but most flagging on YT is down by left wingers. Them crazy #cancelculture ruined most science channels.
Brazil have more than 90% of niobium known reserves.
Sound like they need some freedom!
nah, we good
the guy guy with a full face mask says they don't need freedom.. ok!
99,1%
Yes, we need more freedom and less statism.
Thank God for captions, love these videos
Your videos are great and getting better. Please keep up the good work.
If you want to access the article at 4:46 just visit sci-hub.tw where you can download it for free. It is a really great site which right now provides access to about 65000000 research papers. Of course it's not exactly legal but who cares.
Unpaywall is a legal alternative
The Genesis Library is also a good one.
Fuck the law. Thank you, bro.
researchgate is a good one too.
Oh, and how do you know if the papers weren't altered?
I'll take a look anyway!! 👀
👍you are GREAT 😃👍 thank u so much
Thanks Thoisoi. Great vid, as always.
Great video and experiment, thank you
Wow now we think of car having one color in day and another one in night.This is awesome
It can be done with the thermochromic paint!

i can perfectly understand him, but if you can´t there are subtitels in different languages
I love this effort put in to make these videos. I love the fact that I can learn so many things from you. Lastly, I love your voice!
What will you do when there are no more elements?

They use sodium sesquicarbonate instead to get a smiliar result but with no phosphates
That is one hell of an element! big Thank you to the people who made this excellent channel. You should be sponsored.
A wonderful metals chemistry resource. I have learned so much, Thank You!

interessante, muito bom explanação. Aqui no Brasil, o maior produtor de nióbio, onde possui 98% das reservas do planeta Estamos "ricos", mas ainda não temos tecniologia para processa-lo, em breve chegaremos lá.
Espere sentado.
@@odiverso4407 meu amigo A CBN é o maior podutor mundial de nióbio, e já estão com uma pesquisa avançadissima e em funcionamento para produzir ligas de metais altamentes resistentes como tb a bateria de nióbio... muito mais barata, mais duradoura e que carregam muito mais rapidas que as de lithion.. Se agente não acreditar em nossa capacidade tecnológica, e ficar parado sem estudar, ai sim tem que esperar sentado, deitado ou na próxima encarnação...
Nice info, thank you for sharing it :)
I had no idea about any of this. Thank you for such an informative video.
Loved the memes
Brazil is the highestet source of Niobium.
Is a crazy plan turn de currency over niobium, as same the gold?
Its sell for less a banana Kg
@Google Aids Uai? ou devo dizer With?
Otavio Luis. Niobium is still usefull after a few weeks xD
Quando fala do nióbio tem que falar da cloroquina e da ameaça comunista senão elas ficam com ciúmes.
Omg! I really liked the video! There are a lot of informations that can be used to increase a new research about Niobium! Nice work!
very interesting ! well done for anodising results
I would love to have that dna trinket.
Ashley Cantrell tronket*
Four Twenty, it's trinket my dude :/
Ashley Cantrell never heard someone call it TRINKET before sounds mexican in my area we call em tronkets like a tv tronket a radio tronket etc
Four Twenty, it could be a cultural/language thing? I live in Midwest US and I call it "trinket". if you look it up on Google it says "it's a small ornament or item of jewelry that is of little value"
Ashley Cantrell yeah its probably some small cultural difference or something no mean to offend you but everyone i know in my town in germany says tronket
Nice video! greetings from Turkey
Great Videos, Fascinating subject, Great presentation & narration, Thank you.
Amazing! Had no idea 💡 thanks 😊👍

I love the way he speaks English lol
I like when he says it reacts in the air. First I thought “what!?!!! why should it react in my ear???”
I fuckin hate it because, coupled with him talking like his tongue is too big for his mouth, and I cant barely understand him.
Is THAT what he’s speaking??!
You love when someone speaks English poorly?
@Curt Clark any that are are available, I am an A.I.
because of this chanal i know alot about elements with i didn't even knew if they existed.
very informative! thank you!
WTF I just got a pop-up saying this video is "Inappropriate for some CZcams audiences"!! WHY?!?
Best not to ask, comrade
So you don't Fap to electrolysis and metals being anodized?
Dont tell me you are one of those weirdos attracted to anthropomorphic imagery or sounds depicting 3d humans!
Didn't you see the picture of Niobe at the start? She thicc.
Set the power supply to 80V, wet your hands with the electrolyte, the grab one power supply lead in each hand.......
Because some might find it boring. Lol
How could it replace gold??
Plazor Yeah but it won't cost like gold so its useless to invest money. I was hoping that it will have similar properties of gold that could be used scientifically but turns out its only just color.
If it was possible to make metal have similar properties as gold, it would be all over the news...
DangWeb yeah well this is just gold colored nothing special about it
Its to make for example jewelery look gold. Or make machinery look gold. Why would you need something as soft as gold for? Also gold would probably lose its cost.
Michael Baerga, oh yes there is something special. I have never seen another material that resembles the appearance of gold so closely.
Thank you for all your hard work. I hope kids are more interested in chemistry after watching your beautifully made videos!
Thanks. Really nice work.
Fun fact: 98% of the niobium in the world is from Brazil
Thanks
I got a warning before the video that some users think the video is inappropriate and therefore it is only allowed from the age of 18.
WTF?
Probably because of electrical experiments with voltage higher than 50 Volt DC (considered limit between low/high-voltage systems). 50 Volt DC or less is only mildly annoying on dry skin, whereas higher voltages can be dangerous or lethal, as they can induce heart failure.
In scandinavia nobody is tinkering with things any more. If you do you either get the police on your neck for braking the law or regulations of traffic, radio frequencies, electicity or chemicals. If you even can get the chemicals legaly. Anyway they are going to jail you for attempted terrorism.
Post modern western society rather wants you to have sex on a reality show.
This was your best and most artistic episode.

Nothing replaces gold other than gold
Timmy he’s basically saying that in a mechanical sense, it’s much cheaper than gold and will perform the same way as gold. they would use it as rocket engine parts or parts of machines that would heat to thousands of degrees. not gold jewelry
