Production of more sustainable cement-free magnesia castable by using SioxX®-Mag

The use of cement-free MgO castables offers several advantages, including improved thermal-shock and slag resistance against basic slag, easy installation, and energy savings compared to MgO bricks. Additionally, the substitution of cement binder with microsilica reduces the direct CO₂ footprint.
Furthermore, spent MgO castable can be easily recycled thanks to the forsterite from the interaction between MgO and SiO₂ and no Ca²+ from calcium aluminate cement.
