Products Description
Black silicon carbide powder is an important inorganic non-metallic material with many excellent properties. It is a black powder, translucent, and hexagonal. The Mohs hardness is as high as 9.2~9.5, second only to diamond, and the hardness is between white corundum and diamond. The true density is usually between 3.2~3.45g/cm³. The refractory temperature can reach 1850 degrees, the operating temperature can reach 1900 degrees, and it has good thermal stability. The chemical properties are stable and can withstand the erosion of most corrosive chemicals.
Black silicon carbide powder is usually prepared by the following steps: First, quartz sand, petroleum coke (or coal coke), sawdust and other main raw materials are mixed in a certain proportion. Then, high-temperature smelting is carried out in a resistance furnace to make the raw materials undergo a chemical reaction to generate silicon carbide. The generated silicon carbide blocks are crushed and sieved to obtain silicon carbide powder of different particle sizes. Finally, the silicon carbide powder is chemically treated and washed with water to remove impurities and improve purity.
Due to its excellent properties such as high hardness, stable chemical properties, high thermal conductivity and good wear resistance, black silicon carbide powder has a wide range of applications in many fields: black silicon carbide powder is an important raw material for making abrasives and polishing materials such as grinding wheels, sandpaper, oilstones, grinding heads, and grinding pastes. It can be used for grinding and polishing of metals, stones, glass, ceramics and other materials. Black silicon carbide powder can be used as a refractory material for making high-temperature furnace components and supports. It has the advantages of thermal shock resistance, small size, light weight and high strength. In the metallurgical mineral processing industry, black silicon carbide powder can be used as a deoxidizer and high-temperature resistant material, which helps to speed up steelmaking and control chemical composition. Black silicon carbide powder can be used to make functional ceramics, such as high-temperature non-oxide ceramics, reaction sintering ceramics, etc. It can not only reduce the capacity of kiln furniture, but also improve the quality of kiln products and shorten the cycle. Black silicon carbide powder can also be used to make silicon carbon rods for electric heating elements, and coated on the inner wall of turbine impellers or cylinder blocks to improve wear resistance.
In summary, black silicon carbide powder, as an inorganic non-metallic material with excellent performance, has a wide range of applications and huge market potential in many fields.
