Product Description
92–98% MgO High Temperature Magnesia Refractory Bricks For Glass Kiln Furnace And Rotary Kiln
Magnesium-chrome bricks are refractory products mainly composed of magnesia (MgO) and chromium oxide (Cr₂O₃), with periclase and spinel as the principal mineral phases. They are manufactured using high-purity sintered magnesia and chromite as the primary raw materials.
To ensure excellent performance, the magnesia used should have the highest possible purity. The chemical composition requirements for chromite are as follows: Cr₂O₃ content of 30–45%, and CaO content not exceeding 1.0–1.5%.
