Silicon carbide is a compound of silicon and carbon , also known as carborundum . Silicon carbide nanopowder has larger specific surface area, high purity, and narrow range particle size distribution Silicon carbide has smaller thermal expansion coefficient, better abrasion resistance, chemical stability,and high thermal conductivity Silicon carbide’s mechanical strength is higher than the corundum Silicon carbide nanopowder is a semiconductor and resistant to oxidation in high temperature. In the arts, silicon carbide is a popular abrasive in modern lapidary due to the durability and low cost of the material. In manufacturing, it is used for its hardness in abrasive machining processes such as grinding , honing , water-jet cutting and sandblasting . Particles of silicon carbide are laminated to paper to create sandpapers and the grip tape on skateboards . https://nanografi.com/nanoparticles/sic-silicon-ca... https://nanografi.com/nanoparticles/sic-silicon-ca... ...
