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.
Silicon carbide is made by heating silica sand and petroleum coke packed around electrodes in an electric resistance furnace to above 2200°C. This material is very resistant to abrasion and to corrosion with a molten slag. It also has excellent resistance to thermal spalling. However as it is a carbide, it will oxidise readily. With respect to other refractory aggregates silicon carbide has a fairly high conductivity.
