1700C Corundum Mullite Brick 85-95% Al2o3 Corundum Brick White
Corundum Mullite Brick
Corundum mullite brick is made of fused white corundum, plate corundum, fused mullite and ultrafine powder by high pressure forming and high temperature sintering.Mainly used in glass ceramics, iron and steel, petrochemical, nonferrous and other industries kiln key parts. It has the advantages of high temperature resistance, high compressive strength, high temperature erosion resistance, erosion resistance and so on.
▌FEATURES
1. High temperature resistance;
2. High compressive strength;
3. Strong resistance to erosion;
