Silicon carbide (sic), also known as carborundum, is a compound of silicon and carbon with chemical formula sic. It occurs in nature as the extremely rare mineral moissanite. Silicon carbide powder has been mass-produced since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics  that are widely used in applications requiring high endurance, such as car brakes, car clutches and ceramic plates in bulletproof vests. Electronic applications of silicon carbide as light-emitting diodes (leds) and detectors in early radios were first demonstrated around 1907. Today sic is used in semiconductor electronics applications that are high-temperature, high-voltage or both. Large single crystals of silicon carbide can be grown by the lely method; they can be cut into gems known as synthetic moissanite. Silicon carbide with high surface area can be produced from sio2 contained in plant material.
Black silicon carbide use quartz sand and petroleum coke as the main raw material, smelting the raw material at high temperature electric resistance furnace . Black silicon carbide contains SiC about 95%. The toughness is higher than that of green silicon carbide, black crystals. The microhardness is HV3100-3280kg / mm², brittle and sharp and has a certain electrical conductivity and thermal conductivity. Abrasive made of black silicon carbide is suitable for grinding cast iron, nonferrous metals and rubber, leather, plastic, wood, minerals and other non-metallic materials. Additionally, you can make advanced refractory material and so on.
Green silicon carbie Green silicon carbide is produced as the same type as the black silicon carbide, except the different raw materials.Ití»s crystallization have higher purity and hardness.Green silicon carbide is suitable for processing hard alloy, metallic and non-metallic marterails with hard and brittle feature such as copper, brass, aluminium, magnesslum , jewel, optical glass, ceramics, etc.Super micropower of it is also a kind of ceramics material.
Green Silicon Carbide� is widely used for Abrasive Tools and Sandblasting. Our Silicon Carbide is hard with good abrasive ability and is ideal for abrasive blasting and polishing. It is widely used in abrasive tools, grinding and polishing etc. It also has above 99% Al2O3 content, coarse particles, good self-sharpening and good abrasion resistance.
Black Silicon Carbide  is widely used as a blasting medium and abrasive. Our Silicon Carbide is hard, extremely resistant and able to withstand the strongest alkalis and acids. It is widely used in abrasive tools, grinding and polishing, refractory materials, high end ceramics etc. It also has above 99% Al2O3 content, coarse particles, good self-sharpening and good abrasion resistance.
Green silicon carbide for refractories Green silicon carbide(sic) can also be used for refractory applications because of its high strength, low expansion rate and good thermal conductivity for refractory materials, special ceramics, coating and plastic fillings etc. Physical and chemical properties True gravity: ?3.15 g /cm3 Bulk density: 1.20-1.60 g / cm3 Mosh hardness: ?9 Color: green/light green Melting point: 2700 celcius degree Sizes: 0-1mm, 1-3mm, 3-5mm, 0-10mm etc. Applications of refractory grade green silicon carbide Products of various high grade shaped and unshaped refractory materials Used for semi-conductor deoxidizer Used as deoxidizer in steel making industry to improve quality and productivity of steel Production of silicon carbide rod in electric thermal industry
Silicon carbide elements are used today in the melting of glass and non-ferrous metal, heat treatment of metals, float glass production, production of ceramics and electronics components, igniters in pilot lights for gas heaters, etc Origin - India and China For price, specification and other details please contact us.
Green Silicon Carbide is produced basically in the same way as black silicon carbide in a resistance type electric furnace with petroleum coke, quartz sand and other materials. It has a good hardness, strong cutting ability, stable chemical properties and excellent heat-conducting property.
