Introduction to Silicon Carbide Powder
Silicon carbide is made from petroleum coke and high-quality silica as the main raw materials, with salt as an additive, and is smelted at high temperature in a resistance furnace. The smelted crystal has high purity and high hardness. Its hardness is between corundum and diamond, and its mechanical strength is Higher than corundum.
Compared with black silicon carbide powder, green silicon carbide has advantages in high temperature, electrical insulation and chemical stability.
Silicon carbide has high hardness, high thermal conductivity, good chemical stability and electrical insulation properties, making it widely used in many fields such as abrasives, ceramics, electronic devices, and high-temperature applications.
