Black silicon carbide is a high-quality silica made of quartz sand and petroleum sintered silicon as the main raw materials, which is metallized at high temperature in an electric furnace. It has the characteristics of high hardness, high metal strength, high mechanical strength, and high strength. It is black, translucent, hexagonal, and has a hard silicon content that is almost green. Its physical properties are similar to those of hard silicon, but the performance of solid silicon is better. It also has the characteristics of semiconductor materials and excellent thermal conductivity. Black silicon has a wide range of uses and can be used for low-stress cutting and polishing materials, colored metal abrasives, gray iron building materials, glass, ceramics, stone fireproof products, etc.
Uses of black silicon carbide:
1. Abrasives: sandblasting, surface treatment, silicon carbide nozzles, grinding and polishing of optical glass, hard alloy, titanium alloy and bearing steel, and grinding of high-speed steel tools
2. Grinding tools: resin and ceramic grinding wheels, cutting discs, emery cloth belts, high-temperature silicon carbon rod heating elements
3. Ceramics: high-temperature non-oxide ceramics, reactive sintered silicon carbide ceramics, pressureless sintered silicon carbide ceramics, etc.
4. Refractory materials: refractory linings of smelting furnaces, steelmaking deoxidizers, cast iron organization improvers, refractory bricks, high-temperature furnace components, supports, iron troughs, ladle linings, etc.
5. Electrical and chemical industries: electric heating elements, high-temperature semiconductor materials, far-infrared boards, lightning arrester valve materials, chemical pipelines, valves, etc.
6. Wear-resistant: such as coating on steam/water turbine impellers, wear-resistant pipes, pump chambers, cyclones, ore buckets, highways, airstrip solar water heaters, etc.
