The main crystal phase of corundum is well developed and the microstructure is uniform. Good wear resistance, high density and good corrosion resistance
Mullite phase is formed after calcination. The structural pores are continuously closed, dense and hard. It is an excellent raw material of aluminum silicon refractory
Additives for refractory materials used in various kilns and kiln furniture can effectively improve the high temperature resistance, wear resistance and oxidation resistance of refractory materials
