Black corundum, also known as low aluminum corundum, is a gray-black crystal with α-Al2O3 and iron spinel as the main mineral phase produced by smelting bauxite and iron oxide in electric arc furnace, which is characterized by low Al2O3 content and a certain amount of Fe2O3 (about 10%). Therefore, it has the characteristics of moderate hard bottom, high toughness, high temperature resistance, and hot state performance.
Black corundum black corundum abrasive basic particle concentration, strong cutting force, toughness, hardness and flexibility, good wear resistance, high efficiency.
