Magnesia Zirconia Bricks

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.
