Green silicon carbide is one of the valuable materials in nature. It is mainly used in abrasives, refractory materials and semiconductor materials. Especially in recent years, green silicon carbide micronized abrasive has been widely used for multi-line cutting and grinding in electronic engineering such as single crystal silicon, polycrystalline silicon and piezoelectric crystal. Green silicon carbide is made of quartz sand and petroleum coke as the main raw material, melted at high temperature, green translucent crystals, high hardness, strong cutting power, suitable for processing hard and brittle materials, such as cemented carbide, high-speed steel, ceramics and other non-metals and heating elements, thermal originals.

Main features

High bulk density, strong grinding ability, high hardness, strong cutting ability, concentrated and uniform particle size distribution; high temperature resistance, high strength, good thermal conductivity, impact resistance, as high temperature indirect heating material.

Applications

Green silicon carbide abrasive is widely used in a variety of industries, jade and gemstone polishing, glass, steel, plastic, electronics, mold casting, refractory materials, construction and road building, clothing industry (denim sandblasting), beauty tools, hardware grinding, and also suitable for the manufacture of ceramic abrasive block grinding wheels.

Production process

Green silicon carbide manufacturing method is the same as black silicon carbide, but the purity of the raw materials used requires a higher degree of purity, also formed in the resistance furnace at a high temperature of about 2200 ° C, green, translucent, hexagonal crystal shape, its Sic content is higher than black, physical properties and black silicon carbide similar, but the performance is slightly more brittle than black, also has a better thermal conductivity and semiconductor properties.
