Production and Process of Corundum Bricks

Our Blog
Corundum bricks are refractory products mainly composed of corundum as the primary crystalline phase in the aluminum-silicon system. These bricks possess excellent high-temperature mechanical properties, corrosion resistance, and good abrasion resistance. Matérias-primas: Natural hydrated aluminum oxides, including boehmite and diaspore, can be dehydrated through heating to obtain aluminum oxide (γ-Al2O3). This is then further heated to 1450°C, transforming it into corundum (α-Al2O3). However, due to the limited natural reserves of natural corundum and pure boehmite, industrial alumina is predominantly…
