What is Silicon Carbide (SiC)?
Silicon carbide is divided into green silicon carbide and black silicon carbide. It is smelted at high temperature in a resistance furnace, then processed through crushing, impurity removal, acid washing, water washing, drying and screening. It features stable chemical properties, perfect crystal form, high surface cleanliness, high temperature resistance, high hardness and uniform particle size.

Silicon Carbide (SiC) – Benefits
Silicon Carbide features high purity and ultra-low iron content, which effectively avoids impurity contamination and ensures clean and flawless processing results for all kinds of workpieces. Boasting extremely high hardness and outstanding self-sharpening performance, the material maintains stable and efficient cutting and grinding effects during continuous operation without easy passivation or blockage. It delivers superior heat resistance and thermal shock resistance, with stable working performance at extreme temperatures up to 2000℃, adapting to various high-temperature industrial working conditions. Possessing excellent and stable chemical properties, silicon carbide is resistant to acid and alkali corrosion and will not react chemically with most media in complex industrial environments. The material is equipped with low thermal expansion coefficient and excellent thermal conductivity, which can quickly export heat during processing and effectively prevent workpiece deformation and burnout. It supports a complete and wide particle size range, with customizable standard grit and ultra-fine micropowder specifications that can fully meet the diversified processing and application demands of multiple industries.
