Product Description
Quick Detail:
Leadsun Magnesium Chrome Brick is a high-performance refractory product composed mainly of magnesia (MgO) and chromium oxide (Cr₂O₃), with periclase and spinel as the primary mineral phases. Manufactured using high-purity sintered magnesia and chromite, it offers exceptional resistance to extreme temperatures, slag corrosion, thermal shock, and chemical erosion. Suitable for continuous service above 2000°C, it is widely used in steelmaking, cement kilns, non-ferrous metallurgy, and petrochemical industries.
