black sic crystal
Introduction:
Black Silicon Carbide is produced at high temperature in an electric resistance furnace with quarts sand and petroleum coke as its main raw materials, its hardness is between fused alumina and synthetic diamond. Its mechanical intensity is higher than fused alumina. It is brittle, sharp and has electrical heat conductivity. It is widely used as refractory material and metallurgical additive.
Application:
1. Fixed and moving turbine component
2. Seals, bearings, pump vanes, ball valve parts.
3. Used in refractory industry and metallurgical industry for example kiln furniture etc.
4. Heat exchanger for example electric heat elements.
5. Used as abrasive agent, grinding wheel, sandpaper etc. in abrasive field, it also uses as sharpening abrasive.
6. Other usage: lightening arresters, special seals for chemical processing industry, polishing, ceramics, stone processing, bonded tools, coated tools, etc.

Specifications
- 0-55mm
- In the 1980s and 1990s, silicon carbide was studied in several research programs for high-temperature gas turbines in the United States, Japan, and Europe. The components were intended to replace nickel superalloy turbine blades or nozzle vanes. However, none of these projects resulted in a production quantity, mainly because of its low impact resistance and its low fracture toughness.[28]
- Like other hard ceramics (namely alumina and boron carbide), silicon carbide is used in composite armor (e.g., Chobham armor), and in ceramic plates in bulletproof vests. Dragon Skin, which is produced by Pinnacle Armor, uses disks of silicon carbide.[29]
- F12 - F1200
- Abrasive and cutting tools
- Cutting disks made of SiCIn the arts, silicon carbide is a popular abrasive in modern lapidary due to the durability and low cost of the material. In manufacturing, it is used for its hardness in abrasive machining processes such as grinding, honing, water-jet cutting and sandblasting. Particles of silicon carbide are laminated to paper to create sandpapers and the grip tape on skateboards.[26]
- In 1982 an exceptionally strong composite of aluminium oxide and silicon carbide whiskers was discovered. Development of this laboratory-produced composite to a commercial product took only three years. In 1985, the first commercial cutting tools made from this alumina and silicon carbide whisker-reinforced composite were introduced by the Advanced Composite Materials Corporation (ACMC) and Greenleaf Corporation.[27]
- #240 - #8000
- References to silicon carbide heating elements exist from the early 20th century when they were produced by Acheson's Carborundum Co. in the U.S. and EKL in Berlin. Silicon carbide offered increased operating temperatures compared with metallic heaters. Silicon carbide elements are used today in the melting of non-ferrous metals and glasses, heat treatment of metals, float glass production, production of ceramics and electronics components, etc.[41]
