ISO9001 Black Carborundum Silicon Carbide Block High Temperature Calcination Steel Making Casting Semiconductor

black silicon carbide block high-temperature calcination steel making casting semiconductor

Product name: black silicon

Specification: HY-THG-K

Properties of silicon carbide:
The industrial production method of silicon carbide is to use high-quality quartz sand and petroleum coke in a resistance furnace. The refined silicon carbide blocks are made into products of various particle sizes by crushing, acid and alkali washing, magnetic separation and screening or water separation. There are two basic varieties of silicon carbide, black silicon carbide and green silicon carbide, which belong to α-SiC.
Silicon carbide has stable chemical properties, high thermal conductivity, small thermal expansion coefficient and good wear resistance. In addition to abrasive use, there are many other uses. For example, silicon carbide powder is coated on the inner wall of turbine impeller or cylinder block by special process, which can improve its wear resistance and prolong its service life by 1 ~ 2 times. The advanced refractory material made by it has the advantages of heat shock resistance, small volume, light weight, high strength and good energy saving effect. Low grade silicon carbide ( containing about 85 % SiC ) is an excellent deoxidizer, which can accelerate the speed of steelmaking, facilitate the control of chemical composition and improve the quality of steel. In addition, silicon carbide is also widely used in the production of electric heating element silicon carbon rod. Silicon is a semiconductor with high hardness and excellent thermal conductivity, which can resist oxidation at high temperature.
Silicon carbide has four main application areas, namely : functional ceramics, advanced refractory materials, abrasives and metallurgical raw materials. At present, silicon carbide raw materials can be supplied in large quantities and cannot be counted as high-tech products. The application of nano-scale silicon carbide powder with extremely high technical content cannot form economies of scale in a short time.
