Black silicon carbide powder is a black powder made from silicon carbide (SiC), which is produced by melting silica and petroleum coke or coal coke at high temperature in an electric furnace. With its high hardness, good thermal conductivity and chemical resistance, black silicon carbide powder is widely used in abrasives, refractories, ceramics and other fields. Compared with green silicon carbide, black silicon carbide is slightly lower in hardness but higher in toughness, so it is suitable for a wider variety of processes.
black silicon carbide powder features
1. High hardness: the Mohs hardness of black silicon carbide powder is about 9.2, which is slightly lower than green silicon carbide, but still very hard and suitable for high-intensity processes such as grinding, cutting and polishing.
2. High Thermal Conductivity: Silicon carbide has good thermal conductivity, which allows it to dissipate heat quickly during high-temperature processing, thus improving processing efficiency.
3. Good chemical stability: Black silicon carbide has high chemical stability at high temperatures and is resistant to corrosive substances such as acids, alkalis and salts, so it can be used for applications in corrosive environments.
4. Higher toughness: Compared with green silicon carbide, black silicon carbide has better toughness, so it is not easy to break in cutting, grinding and other operations, extending its service life.
5. RELATIVELY LOW COST: The production cost of black silicon carbide powder is relatively low, and it is often used in large-scale industrial production with high cost requirements.
black silicon carbide powder adavantages
- Efficient Grinding: Black Silicon Carbide Powder is able to efficiently grind harder materials and reduce processing time due to its balanced hardness and toughness.
- Durability: Its stability in high temperatures and corrosive environments allows it to excel in a wide range of harsh working conditions, extending its service life.
- Wide applicability: Black silicon carbide powder can be used in a wide range of machining and manufacturing processes, making it suitable for a variety of applications from heavy industry to fine chemicals.
black silicon carbide powder application
1. Abrasives: Black silicon carbide powder is widely used in the manufacture of a variety of abrasives, grinding wheels and abrasive materials. It can effectively polish metal, stone, glass and ceramics, and is especially suitable for materials with high hardness and toughness.
2. Refractories: Due to its high temperature resistance and chemical corrosion resistance, black silicon carbide powder is used to produce high temperature furnace linings, refractory bricks, crucibles and other refractory materials, which are suitable for use in high-temperature metallurgical furnaces, chemical equipment and other fields.
