Black fused alumina, also known as low-aluminum fused alumina, is a gray-black crystal with α-Al2O3 and iron spinel as the main mineral phases, which is obtained by smelting bauxite in an electric arc furnace. It is characterized by low Al2O3 content and a certain amount of Fe2O3 (关于 10%), so it has the characteristics of moderate hardness, 高韧性, 耐高温, and stable thermal performance. It is mostly used for free grinding, such as grinding and rough grinding before electroplating of products, mainly used for polishing and sandblasting of stainless steel, 金属制品, 光学玻璃, 竹木制品, and is also a novel abrasive for manufacturing resin grinding wheels, 切割片, and emery cloths.
