Silicon carbide powder is an extremely hard abrasive material. It always works as raw abrasive grits for sanding paper, grinding wheels, etc. For its high wear resistance, Silicon carbide powder performs well as pistol grip for hunting guns. It can enhance the friction between the hand and the grip.
Silicon carbide is not only an excellent refractory material. But also it is a commonly used grinding material, anti-corrosion material, and thermally conductive material. The main chemical of silicon carbide is SiC, with another name carborundum. It gets many excellent properties.
Silicon carbide powder is famous for its high refractory temperature, hardness, and chemical stability. At the same time, the thermal conductivity of silicon carbide is also an important reference index for many related applications. The thermal conductivity of high-purity silicon carbide crystals is 1490 W/M · K. The thermal conductivity of silicon carbide obtained through high-temperature smelting varies with temperature. The higher the temperature, the lower the thermal expansion coefficient. Overall, the thermal conductivity of silicon carbide ranges from 60 to 200 W/M · K. After making silicon carbide ceramics, the thermal conductivity is about 40-220W/M · K. The thermal conductivity of silicon carbide powder is several times that of corundum.
Recently, the research team of the Laboratory of Precision Optical Manufacturing and Testing Center of Shanghai Institute of Optics and Precision Machinery, Chinese Academy of Sciences, has made progress in the research on improving polishing efficiency by femtosecond laser modification of silicon carbide surface.
Black silicon carbide 16 # refers to the material made by high-temperature reaction of silica sand and Petroleum coke material. During production, the black abrasive with a particle size of 16 meshes (that is, a diameter of about 1.18mm) is obtained after screening.
The main functions of engine oil are lubrication, cooling, rust prevention, sealing, etc. The main purpose of lubricating oil is to lubricate the engine, reduce engine wear, lower engine temperature, and prevent parts from rusting. At the same time, the oil also needs to maintain appropriate viscosity, dispersibility, and high-temperature stability. Black silicon carbide powder is a wear-resistant, oxidation-resistant, high-temperature-resistant, and high thermal conductivity material. Black silicon carbide F240 and F320 can greatly help the function of engine oil.
