Silicon Carbide SIC
The black crystal silicon carbide with high density produced in our plant is made from high purity quartz sand and petroleum coke. The products are melted through high temperature up to 2500C in the electronic furnace. The products have high hardness good thermal endurance wear resistance, radiation resistance, thermal shock resistance, and good electrical and thermal conductivity,and are widely used in engineering ,chemistry ,electronic ,metallurgy and defense industries. Our company can produce different sizes of silicon carbide, according to the national and international standards GB,ISO,ANSI,FEPA,JIS, etc.
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. Synthetic 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 such as light-emitting diodes (LEDs) and detectors in early radios were first demonstrated around 1907. SiC is used in semiconductor electronics devices that operate at high temperatures or high voltages, 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.
(1)Large melting furnace, longer melting time, lead to more crystallization, bigger crystals, higher purity and less impurities in producing Silicon carbide.
(2) Character of Silicon carbide: Good hardness, longer life.
(3) Chemical washed and water washed good cleanness.
(4) Special treated for Silicon carbide get higher purity, better toughness, and better grinding effect.
Silicon carbide can be used as metallurgical deoxidizer and high temperature resistant materials in smelting.
Silicon carbide can also be used as abrasive materials,which can be used to make abrasive tools,such as grinding wheels, oilstones, grinding head and so on.
Silicon carbide is a new kind of reinforced steelmaking deoxidizing agent and ideal thermal insulating agent.it is used for deoxidizing. The usage dose is 14kg/t can make electricity consumption to reduce 15-20kw/h and time to reduce 15-20min per furnace to raise productivity rate to 8-10%.
