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.

Silicon carbide for advanced refractory material The main application in the refractory industry is more, of course, other industries can also be applied. Silicon carbide has high fire resistance and chemical stability, Therefore, it is widely used in all kinds of refractory materials, but there is no complete method of chemical analysis of silicon carbide refractories. Analysis of the project of SiC Refractory general: free carbon, silicon dioxide, silicon carbide, silicon, alumina and ferric oxide free three. The utility model is mainly used in the refractory industry, the deoxidizing agent in the steel making industry, the gun mud, the casting material and the iron channel material. The content distribution of this product is: 98% 97% 95% 90% The material has good wear resistance, thermal shock stability, volume stability and strength, thermal conductivity is also very good. In addition, the material also has Good performance, such as simple site preparation, rapid growth of strength, easy to follow-up construction and bonding with metal components, such as solid. Cyclic vulcanization The lining of the combustion chamber of the boiler and the inlet of high temperature separation. 1-3, 1-0.2180-0,0.2-0,0-1 refractory with silicon carbide as the main component. Density 3.1/cm3. Thermal expansion coefficient 3.7 thermal conductivity 0.6 using hot pressing sintering method. Can be used for all kinds of smelting furnace lining, high-temperature furnace components, silicon carbide plate, plate, support, sagger, carbide Silicon crucible. Heavy refractory material made of SiC95% as the main raw material of the crystallization of refractory materials. Due to the high purity of raw materials, low melting impurities The high temperature performance of the product is much better than that of the clay binding product, but the high temperature performance of the product is also affected by the forming pressure and the like Art influence.
