Silicon Carbide
Silicon carbide powder features: black silicon carbide is made of quartz sand, petroleum coke (or coal coke), wood chips and other raw materials in the resistance furnace by high temperature smelting, in the resistance furnace by high temperature smelting, black opaque body, hexagonal crystal, brittle and sharp performance and have a certain electrical conductivity, brittle and sharp, and has good thermal conductivity and electrical conductivity.
High quality dense silicon carbide product content of more than 98%. Black silicon carbide is made of high-grade refractory material, heat resistance, small size, light weight and high strength, good energy saving effect. Silicon carbide is also widely used to make silicon carbon rods for electric heating elements. The raw materials used in black silicon carbide have higher purity requirements and similar physical properties to green silicon carbide, but the performance is slightly more brittle than black, and it also has better thermal conductivity and semiconductor characteristics.
Due to its stable chemical properties, high thermal conductivity, low thermal expansion coefficient, and good wear resistance,silicon carbide has many other uses besides being used as abrasives. For example, silicon carbide powder is applied to the impeller or cylinder of a water turbine by a special process. The inner wall can improve its wear resistance and prolong its
service life by 1 to 2 times; the high-grade refractory material made of it has heat shock resistance, small size, light weight, high strength and good energy-saving effect. Low-grade silicon carbide (containing about 85% of SiC) is an excellent deoxidizer.
It can speed up the steelmaking speed, and facilitate the control of chemical composition and improve the quality of steel. In addition, silicon carbide is also widely used to make silicon carbide rods for electric heating elements.

Element content, packaging, and particle size can be customized according to customer requirements.
Silicon carbide has four main application areas, namely: functional ceramics, advanced refractories, abrasives and metallurgical raw materials. Coarse silicon carbide materials can already be supplied in large quantities and cannot be regarded as a high-tech product. The application of nano-scale silicon carbide powder with extremely high technical content is unlikely to form economies of scale in a short time.
1.As an abrasive, it can be used to make abrasive tools, such as grinding wheels, oilstones, grinding heads, sand tiles, etc.
2.As a metallurgical deoxidizer and high temperature resistant material.
3. High-purity single crystals can be used to manufacture semiconductors and silicon carbide fibers.
Main application: used for wire cutting of 3-12 inch monocrystalline silicon, polycrystalline silicon, potassium arsenide, quartz crystal, etc. Engineering processing materials for the solar photovoltaic industry, semiconductor industry, and piezoelectric crystal industry.
Used in semiconductors, lightning rods, circuit components, high temperature applications, ultraviolet light detectors, structural materials, astronomy, disc brakes, clutches, diesel particulate filters, filament pyrometers, ceramic films, cutting tools, heating elements, nuclear fuels , Jewelry, steel, protective gear, catalyst carrier and other fields.
