Green silicon carbide powder is quartz sand. Petroleum coke is the main raw material, which is smelted by resistance furnace at high temperature. Its hardness is between corundum and diamond, its mechanical strength is higher than corundum, and it is brittle and sharp. It has certain electrical and thermal conductivity. Green silicon carbide powder has green appearance, crystal structure, high hardness, strong cutting ability, stable chemical properties and good thermal conductivity.

Green silicon carbide powder has good self-sharpening and excellent grinding and polishing properties. In recent years, with the development of the world's semiconductor industry, green silicon carbide micropowder is mainly used in multi-wire cutting and grinding in electronic engineering such as single crystal silicon, polycrystalline silicon, and piezoelectric crystals. For wire cutting of 3-12 inch monocrystalline silicon, polycrystalline silicon, potassium arsenide, quartz crystals. It is an engineering processing material for solar photovoltaic industry, semiconductor industry and piezoelectric crystal industry.

Green silicon carbide powder is a high-purity silicon carbide grinding powder with excellent chemical stability at room temperature. At present, silicon carbide micropowder is mainly 1200# and 1500#. Since silicon carbide micropowder is mainly used in the abrasive industry, there are special requirements for the classification of micropowder. Large particles cannot appear in the micropowder. Therefore, in order to meet the international and domestic product requirements, - In general production, JZF grading equipment is used for high-precision grading.

The so-called quality of green silicon carbide powder depends on demand. 1200 and 1500 are the mesh numbers. The larger the mesh number, the smaller the particles. If 1500 silicon carbide is required, the central value should be 8.5 microns, and the quality depends on whether the particle size in this range is relatively concentrated.
