Magnesia Zirconia Bricks belongs to alkaline refractory bricks products, one of the magnesia refractory bricks. This product uses high-purity fused magnesia and synthetic magnesia zircon sand as raw materials, and is formed by high pressure and high temperature firing. In its microstructure, the main mineral phases are periclase, forsterite and zirconia, which have excellent corrosion resistance to alkali metals, oxides and sulfides. RS Magnesia Zirconia Bricks service life reaches more than eight years.
About Magnesia Zirconia Bricks
Magnesia Zirconia Bricks use high-purity fused magnesia and synthetic magnesia-zircon sand as raw materials. After high pressure molding and high temperature firing, it has excellent corrosion resistance to alkali metals, oxides and sulfides. Magnesia-zirconium bricks are made of fused magnesia and zircon sand and the alkaline materials to which they belong. It has a high density (bulk density) greater than 3.08 g / cm3.
Features of Magnesia Zirconia Bricks
- ♦ Alkali resistance
