Introduction of black silicon carbide micropowder:
Black silicon carbide micro powder is a fine-grained substance made from ground silicon carbide grains. Its chemical formula is SiC, which is an important inorganic material. Black silicon carbide micropowder is made of quartz sand, petroleum coke (or coal coke), wood chips and other raw materials in the resistance furnace by high-temperature smelting, after acid and alkali washing and other chemical treatments, and then in the crushing, screening and other processes to reach the small particles and powders to be screened again, the treatment of black silicon carbide in line with the requirements of the microparticle again hydraulic overflow grading process or siphon grading process, unlike the process, the process of water washing process to produce the The yield and fineness of black silicon carbide micropowder particles are different, the composition of silicon carbide micropowder mainly contains: silicon carbide, iron trioxide, carbon, silicon, silicon dioxide, aluminium, PH, conductivity and other content. So silicon carbide is very hard, has excellent thermal conductivity, is a kind of semiconductor, high temperature also does not lose oxygen.

To choose the right silicon carbide abrasive, consider factors like the material being worked on, the desired finish, the abrasive life, and the equipment being used. Generally, harder materials require finer grits, while softer materials can be worked with coarser grits.
Grit sizes for silicon carbide abrasives range from coarse (24 grit) to ultrafine (1200 grit) and are used for different applications, from rapid material removal to precision polishing.
Silicon carbide abrasives are harder and sharper than aluminum oxide abrasives, making them more aggressive and faster cutting. However, they are also more brittle, which can lead to faster breakdown and shorter abrasive life.
