Black Silicon Carbide Powder
Black Silicon Carbide Powder
Black Silicon Carbide Powder is an abrasive material composed of silicon carbide, which is a crystalline compound of silicon and carbon. It has a dark color and is often used for grinding, cutting, and polishing applications due to its high hardness and abrasive properties.
Black Silicon Carbide Powder is made by smelting high-purity quartz sand and petroleum coke in an electric resistance furnace. The resulting mixture is then crushed and ground into a fine powder. It has a hardness of 9.5 on the Mohs scale, which makes it one of the hardest materials used in abrasive applications.
Black Silicon Carbide Powder is commonly used for grinding and polishing metals, ceramics, and other materials. It is also used in the production of refractory materials, as well as in the manufacture of semiconductors and other electronic components.
Due to its high hardness and abrasive properties, Black Silicon Carbide Powder is also used in the manufacturing of grinding wheels, sandpaper, and other abrasive products. It is an excellent choice for applications that require fast and efficient material removal, as well as for applications that require a high-quality surface finish.
Overall, Black Silicon Carbide Powder is a versatile and high-performance abrasive material that is used in a wide range of industrial applications. Its unique properties make it ideal for applications that require fast and efficient material removal, as well as for applications that require a high-quality surface finish.

Silicon Carbide Ceramics Applications
Until the invention of boron carbide in 1929, silicon carbide was the hardest synthetic material known. It has a Mohs hardness rating of 9, approaching that of a diamond. In addition, SiC crystal has fracture characteristics that make them extremely useful in grinding wheels and in abrasive paper and cloth products.
Its high thermal conductivity, together with its high-temperature strength, low thermal expansion, and resistance to chemical reaction and thermal shock, makes silicon carbide valuable in the manufacture of high-temperature bricks and other refractories.
SiC ceramic is also classed as a semiconductor, having an electrical conductivity between that of metals and insulating materials. This property, in combination with its thermal properties, makes SiC a promising substitute for traditional semiconductors such as silicon in high-temperature applications.
