Silicon carbide is an inorganic substance with the chemical formula SiC. It is smelted at high temperature in a resistance furnace using raw materials such as quartz sand, petroleum coke (or coal coke), and wood chips (salt is required when producing green silicon carbide). Silicon carbide also exists in nature as a rare mineral, moissanite. Among non-oxide high-tech refractory raw materials such as C, N, and B, silicon carbide is the most widely used and economical one, and can be called emery sand or refractory sand. Silicon carbide produced industrially in China is divided into black silicon carbide and green silicon carbide. Both are hexagonal crystals with a specific gravity of 3.20~3.25 and a microhardness of 2840~3320kg/mm2.
Application scope
Silicon carbide has four main application areas, namely: functional ceramics, advanced refractory materials, abrasives and metallurgical raw materials. Silicon carbide rough materials can already be supplied in large quantities and cannot be considered high-tech products. However, the application of nano-scale silicon carbide powder with extremely high technical content cannot form economies of scale in a short time.
⑴ As an abrasive, it can be used to make abrasive tools, such as grinding wheels, oil stones, grinding heads, sand tiles, etc.
⑵ As metallurgical deoxidizer and high temperature resistant material.
⑶ High-purity single crystal can be used to manufacture semiconductors and silicon carbide fibers.
Main uses: used for wire cutting of 3-12 inch monocrystalline silicon, polycrystalline silicon, potassium arsenide, quartz crystal, etc. Engineering processing materials for solar photovoltaic industry, semiconductor industry, and piezoelectric crystal industry.
Used in semiconductors, lightning rods, circuit components, high temperature applications, UV detectors, structural materials, astronomy, disc brakes, clutches, diesel particulate filters, filament pyrometers, ceramic membranes, cutting tools, heating elements, nuclear fuel , jewelry, steel, protective gear, catalyst carrier and other fields.
