Black silicon carbide/carborundum blocks for refractory
Silicon carbide is made of quartz sand, stone tar (or coal), wood chips and other raw materials in the resistance by high temperature smelting, silicon and carbon bonds made of ceramic compounds. Silicon carbide exists in nature in the form of rare minerals such as mozanite. Since 1893, silicon carbide powder has been used extensively as abrasive. The sintered silicon carbide powder can provide hard ceramic-like silicon carbide particles and can be used in materials such as automotive brake pads, clutches and ballistic vests that require high durability, such as light-emitting diodes, early radio detectors Classes are also used in the manufacture of electronic devices. Silicon carbide is now widely used in the manufacture of high temperature, high voltage semiconductors. By lely method to grow large pieces of silicon carbide single crystal. The gemstone of artificial mulberry is obtained by cutting the bulk silicon carbide single crystal prepared by the Lely method.
       At present, China's industrial production of silicon carbide is divided into black silicon carbide and green silicon carbide two, are hexagonal crystal, green silicon carbide and black silicon carbide is basically the same, but the raw materials and manufacturing processes are produced, the product was green translucent body , Hardness, purity are better than black silicon carbide.

Silicon carbide as inorganic nonmetallic materials with high temperature resistant, wear resistant characteristics of silicon nitride combined with silicon carbide products can be used in the blast furnace ceramic cup, etc.In air brick as ladle with magnesia carbon brick, aluminum silicon carbide can also act as antioxidants added.
Made of silicon carbide refractory plate high crushing strength, long service life, low thermal capacity, low thermal conductivity.The brittle material, good toughness;Good flatness, size accurate,Easily cut installation, construction is convenient;Excellent resistance to wind erosion performance;Continuous production, uniform fiber distribution, stable performance;Excellent sound-absorbing noise reduction performance.
Â
Third: steel making, casting industry (particles of silicon carbide, silicon carbide, silicon carbide, silicon carbide powder)
Silicon carbide as steelmaking deoxidizer can make molten steel quality is stable, and has fine grains, remove steel always harmful impurities, after using molten steel casting temperature, casting are of good quality and low cost per unit.
Silicon carbide can be all alternative ferrosilicon and recarburizer FeALSi dosage decreased, which can effectively reduce the cost of steelmaking.
Decomposition of silicon carbide at high temperature and oxidation is exothermic reaction process, positive pressure in the furnace is strong, and can guarantee lower sulfur content.
Â
Fourth: photovoltaic industry, polishing, grinding, high-tech research and development, and other industries (silicon carbide micro powder)
Silicon carbide powder is mainly used for refractory products manufacturing, and foam ceramic industry, solar silicon original cutting, crystal cutting, grinding, car engine manufacturing, special coating industry, plastics modification, desulfurization, power supply, environmental protection industry, etc.
