Product Introduction
Magnesia alumina spinel bricks are made from high-purity magnesia sand and fused magnesia alumina spinel through special processes. Due to the use of "in-situ spinel" technology and high-purity raw materials, the product has high strength, strong wear resistance, anti peeling, and anti erosion characteristics under high temperature conditions.
