Black fused alumina, also known as black aluminum oxide, is a type of abrasive material that is commonly used in various industrial applications. It is made from the high-quality bauxite ore by fusing it in an electric arc furnace at high temperatures. During this process, the aluminum oxide content in the bauxite is reduced, resulting in a material that is predominantly composed of aluminum oxide and iron oxide.
*Color and Appearance: As the name suggests, black fused alumina is black in color. It has a matte appearance and a high hardness.
*Hardness: Black fused alumina is known for its high hardness, making it suitable for abrasive applications. It is often used for cutting, grinding, and polishing metals, ceramics, and other materials.
*Abrasive Properties: It is an abrasive material with excellent cutting and grinding properties. It is used in applications such as sandblasting, grinding wheels, abrasive belts, and abrasive powders.
*Strength and Durability: It has good strength and durability, making it a reliable choice for applications where wear resistance is essential.
*Chemical Composition: Black fused alumina typically contains aluminum oxide (Al2O3) as the primary component, along with iron oxide (Fe2O3) and small amounts of other impurities.
