Black Fused Alumina

Product Induction：

Our Black Fused Alumina is a dark gray crystal body made α-Al2O3 and ferropicotite as main ore in the electric arc furnace by smelting the bauxite .Its character is that the content of Al2O3 is low, and there is a certain amount of Fe2O3, there is a small amount of SiO2 and TiO2. It also has the characteristics of moderate hardness, high toughness, high temperature resistance and stable thermal performance. It is mostly used for free grinding, such as the grinding and polishing of stainless steel, metal products, optical glass, tableware and cookware, bamboo and wood products, and is also widely used in consolidated abrasives and coated abrasives.
