Zirconia-corundum brick is a type of fused-cast refractory material mainly composed of alumina, zirconia, and silica. It is produced through an electric fusion and casting process, resulting in a compact and dense structure with excellent high-temperature corrosion resistance.
This product is widely used in high-grade glass melting furnaces.
