Green Silicon Carbide

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 can also be called SiC. There are black silicon carbide and green silicon carbide. According to the shape, there are silicon carbide blocks and silicon carbide powder. The common method is to mix quartz sand with coke, use the silica and petroleum coke, add wood chips, put it into an electric furnace, heat it to a high temperature of about 2000 C, and obtain silicon carbide after various chemical processes. To green silicon carbide, add salt. Application: Silicon Carbide is widely used in the fields of Abrasive,Grinding, Metallurgy, Refractory, Ceramics, Petroleum, Chemical, Microelectronics, Automobile and Aerospace and so on. The main field of application: 1. Nonferrous metal Smelting industry. 2. Steel line using 3. Energy-saving line 4. Instead of fe-si for smelting steel,not only can remove Oxygenbut also can raise the temperature of molten steel. 5. Lining of high furnace to improve furnace age. 6. Stemming,downspouting and all kinds refractory brick of high furnace. 7. Iining of Electric tank of Electrolytic Aluminium or total tank body made by sic. 8. Silicon carbide ceramics is made by high quality sic fine powder firing several wearproof,acid- resisting and high temperature resistance parts. 9. Filling up material for high way and airport runway to make road surface skidding resistance and wear meanwhile improving using age. 10. High purity material can be used in producing Seni-conductor,Sic fabrics and so on. Specifications: Grade Chemicals  Composition(%) Sic Fe2O3 F�·C.

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.

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.

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.

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.

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.
