Silicon Carbide

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.

Silica, silicon carbide, silicon carbide, also known as carbon refractory sand, is made of quartz sand and petroleum coke, sawdust and other raw materials in smelting in electric resistance furnace, high temperature and be become.Green silicon carbide black silicon carbide and silicon carbide two commonly used basic varieties: (1) black silicon carbide containing SiC by about 95%, its toughness is higher than the green silicon carbide, mostly used for processing low tensile strength of material, such as glass, ceramics, stone, refractory material, cast iron and nonferrous metal, etc.;(2) the green silicon carbide containing SiC98 % above, good self-sharpening, mostly used for processing hard alloy, titanium alloy and optical glass, also used for honing cylinder jacket and fine grinding HSS cutting tools.

1, Main silicon carbide abrasive, stability of high hardness, toughness determined by sic grinding tool can be used in the manufacture of consolidation, coated abrasive free grinding glass, ceramics, stone, cast iron and some non-ferrous metals, hard alloy, titanium alloy, high speed steel cutter grinding wheel, etc. 2, Refractory corrosion resistant material - main silicon carbide with high melting point (temperature), chemical inert reting resistance silicon carbide can be used for abrasive, ceramic products by burning kiln with shed board saggar, zinc smelting industry vertical cylinder distillation furnace with carbon silica brick, aluminum electrolytic cell line, crucible, such as a furnace material of silicon carbide ceramic products. 3, Chemical use, silicon carbide steel melt steel hydrolysis and free oxygen, metal oxide reaction of carbon containing silicon oxide slag for smelting steel cleaning agent is used for steelmaking deoxidizer cast iron tissue conditioner, generally with using low purity of silicon carbide to reduce the raw material for manufacturing silicon tetrachloride. 4, Electrical use, used for high temperature heating element, nonlinear resistance element semiconductor material silicon carbide heating element used in the 1100 ~ 1500 (furnace) nonlinear resistance element all kinds of lightning protection valve plates. 5, The far-infrared radiation coating or silicon carbide silicon dryer with far infrared radiation. New silicon carbide products is widely used in a particular industry, air conditioning, automotive engine, communications equipment, radar stations, the missile defense system, the space shuttle, and are used on aircraft carrier, especially in the aspect of space, some special parts, silicon carbide products to be reckoned with, and the effect of foreign resources, has the advantages of domestic, therefore, the development of an opportunity is also relatively well.

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.

This silicon carbide crucibles are used to produce sponge iron based on tunnel kilns. Main sponge iron market is India, Iran and Mexico.

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
