Green silicon carbide particle size sand 46 mesh, 54 mesh, 60 mesh 80 mesh

green silicon carbide particle size sand 46 mesh 54 mesh 60 mesh 80 mesh The production method of green silicon carbide powder is basically the same as that of black silicon carbide, but the requirements for raw materials are different. Green silicon carbide is made of petroleum coke and high-quality silica as the main raw materials, adding salt as an additive, smelting by high temperature resistance furnace, the crystals smelted into high purity and hardness, its hardness is between corundum and diamond, and the mechanical strength is higher than corundum.

Green silicon carbide1Abrasive–mainbaiIt is because silicon carbide hasduHigh hardness, chemical stability and certain toughnesszhi, so carbondaoSilicon can be used to manufacture consolidated abrasives, coated abrasives and free grinding to process glass, ceramics, stone, cast iron and some non-ferrous metals, cemented carbide, titanium alloys, high-speed steel tools and grinding wheels.

2, refractory materials and corrosion-resistant materials—Mainly because silicon carbide has a high melting point(Decomposition), chemical inertness and thermal vibration resistance, so silicon carbide can be used in abrasives, ceramic products firing kiln used in the shed and box, zinc smelting industry vertical cylinder distillation furnace silicon carbide bricks, aluminum electrolytic cell lining, crucibles, small furnace materials and other silicon carbide ceramic products.

3, chemical use–Because silicon carbide can decompose in molten steel and react with oxygen separation and metal oxides in molten steel to form carbon monoxide and silicone-containing slag. Therefore, it can be used as a purifying agent for smelting steel, that is, as a deoxidizer for steelmaking and a cast iron structure improver. This generally uses low-purity silicon carbide to reduce costs. At the same time, it can also be used as a raw material for the manufacture of silicon tetrachloride.

4, electrician use–Used as heating elements, nonlinear resistance elements and high semiconductor materials. Heating elements such as silicon carbon rods(Applies to1100~1500℃Various electric furnaces for work), nonlinear resistance elements, various lightning arresting valve plates.

5, other formulated into far-infrared radiation coating or made of silicon carbide silicon board with far-infrared radiation dryer.
