Products Description
Black silicon carbide powder is an important industrial material, its main components are silicon and carbon, and its chemical formula is SiC. This material has a wide range of applications in many fields due to its unique physical and chemical properties. The Mohs hardness of black silicon carbide powder is as high as 9.15-9.5, second only to diamond, and has good wear resistance and scratch resistance. The crystal structure of black silicon carbide is stable, and it can maintain excellent physical and chemical stability at high temperatures. It can work normally even at a high temperature of 1850℃ and maintain good performance at 1400℃.
At high temperatures, a layer of silicon dioxide film will form on the surface of black silicon carbide powder particles, which effectively prevents the oxidation of silicon carbide and resists the erosion of strong acids and alkalis, so it has excellent corrosion resistance and high-temperature oxidation resistance. Black silicon carbide powder has good thermal conductivity and can quickly disperse heat. At the same time, its low thermal expansion coefficient helps to maintain the stability of the material at high temperatures.
Black silicon carbide powder is widely used for grinding metal and non-metal materials, such as alloys, silicon wafers, ceramics, jade, etc., especially on occasions with strict requirements on surface roughness. Black silicon carbide powder can provide the required particle size according to the process. As a fine powder with very high hardness, black silicon carbide powder is often added to coatings, resins, special plastics, or other composite materials to improve the wear resistance of the materials, and it is very helpful for the strength, corrosion resistance and high-temperature resistance of the products. Black silicon carbide powder can be used to make high-temperature anti-corrosion coatings and thermal insulation building materials, which play a role in heat insulation and fire prevention. At the same time, it can also be used as a raw material for anti-corrosion mortar and is used in thermal, electric power and other industries. After industrial ceramics are mixed with black silicon carbide particles, they can be made into sintered silicon carbide ceramic parts to improve the density and performance of silicon carbide ceramics.
Black silicon carbide powder is the main raw material for abrasive products such as water sandpaper and rubber grinding wheels. It is used to manufacture various silicon carbide ceramic products, such as abrasive tools, shelves and saggers in kilns for firing ceramic products, silicon carbide bricks for vertical cylinder distillation furnaces in zinc smelting industry, etc. It can be used as a purifier for smelting steel, that is, as a deoxidizer for steelmaking and a cast iron structure improver. At the same time, it can also be used as a raw material for manufacturing silicon tetrachloride.
