Black silicon carbide sand is how the division number number, different size of SiC, models from 14# to 240# is called open end silicon carbide sand particle size of sand. The use of silicon carbide is the result of market development of photovoltaic industry, polishing and grinding, abrasive and other industries are obtained, there are a lot of silicon carbide characteristics, especially for silicon carbide with high grinding, corrosion resistance and high temperature resistance, high strength, good thermal conductivity etc.. It's very important for polishing jade articles, stainless steel, glass, precious stones and so on.

Application of black silicon carbide and green silicon carbide is a difference in the use of the black silicon carbide sand particle size in cutting, grinding of brittle non-metallic materials is good material, such as glass, ceramics, floor tile, stone, refractory materials, grinding cast iron and some non-ferrous metal parts. The industrial process of silicon carbide is the use of high-quality quartz sand and petroleum coke in the resistance furnace refining. Blocks of refined silicon carbide, crushing, acid wash, magnetic separation and sieving or water products made of various size. The commonly used silicon carbide particle size: 16# - 400#, is formed on the surface of the mould surface texture, such as cleaning very hard: tungsten carbide workpiece; used in deep sand carving, stone carving, such as thin and brittle workpiece cutting blasting.

 

Silicon carbide has four major application areas, namely: ceramics, advanced silicon carbide, refractories, abrasives and metallurgical raw materials. Widely used in sand blasting, grinding and polishing, emery wear-resisting flooring, precision casting mold shell production. At present, there is a large supply of silicon carbide coarse materials, which can not be regarded as high-tech products, and the application of nanometer silicon carbide powders with high technical content can not form economies of scale for a short time. As abrasive, can be used for abrasive, such as grinding wheel, stone, grinding head, sand tile, etc.. As a metallurgical deoxidizer and a high temperature resistant material, high-purity single crystals can be used in the manufacture of semiconductors and in manufacturing silicon carbide fibers.
