Corundum brick

Corundum brick with alumina content greater than 90% and corundum as the main crystalline phase. High compressive strength at room temperature (up to 340MPa). High load softening initial temperature (greater than 1700℃). Good chemical stability, strong resistance to acidic or alkaline slag, metal and liquid glass. Divided into sintered corundum brick and fused corundum brick two kinds. Sintered alumina and fused corundum can be used as raw materials, or alumina clinker with high Al₂O₃/SiO₂ ratio can be combined with sintered alumina by sintering method
