A refractory product having a alumina content of more than 90% and a corundum-based crystal phase. Very high room temperature compressive strength (up to 340MPa). High load softening onset temperature (greater than 1700 ° C). Very good chemical stability, strong resistance to acidic or alkaline slag, metal and glass. The thermal shock stability is related to its structure, and the corrosion resistance of the compact product is good, but the thermal shock stability is poor.Application:
Widely used in the cracking, reforming furnace, metallurgical industry and other high-temperature kiln linings and kiln furniture in the petrochemical and fertilizer industries.
