Introduction of black silicon carbide:

Black silicon carbide ( SiC ), also known as gold steel sand or refractory sand, is black crystalline, brittle and sharp, and has certain thermal conductivity and electrical conductivity. As an abrasive, it is second only to diamond, cubic boron nitride and boron carbide. The preparation process of black silicon carbide is the same as that of green silicon carbide. It is made of quartz sand, petroleum coke and high-quality silica as the main raw materials and smelted by high pressure resistance furnace.
Because of its stable chemical properties, high thermal conductivity, small thermal expansion coefficient and good wear resistance, black silicon carbide can be used as
1.It can be used as abrasive, abrasive tool, optical glass, cemented carbide, titanium alloy and bearing steel grinding and polishing and high speed steel tool grinding. Black silicon carbide is mostly used for cutting and grinding materials with low tensile strength. It is used for crystal cutting and precision grinding, precision grinding of hard glass, slicing of monocrystalline silicon and polycrystalline silicon rods, precision grinding of monocrystalline silicon wafers, processing of superhard metals, processing of soft metals such as copper and copper alloys, and making consolidated abrasives and coated abrasives. ;
2.it is mainly used for high-temperature furnace components and supporting parts, and has good energy-saving effect. 2 It is made into advanced refractory materials, which are resistant to thermal shock, small in size, light in weight and high in strength.
3. As a functional ceramic, it can not only reduce the capacity of kiln furniture, but also improve the quality of kiln products and shorten the cycle. It is an ideal indirect material for ceramic glaze baking and sintering.
4. in the non-ferrous metal industry, in addition to a variety of smelting furnace lining, also used as steelmaking deoxidizer, cast iron structure modifier ;
5. In the electrical industry, black silicon carbide materials are also widely used as electric heating elements, high temperature semi-superconductor materials, far infrared plate, arrester valve plate materials.
