Silicon Carbide Ceramics Production Process

Most of the silicon carbide ceramic powders used today are synthetic, because natural silicon carbide ceramic powders do not exist on earth, they are only found in meteorites, and the human use of silicon carbide ceramics is really large, so the synthesis work is very important. The method of Acheson or the chemistry method and the thermal decomposition method are generally used, where Acheson is a high temperature reaction by electricity to achieve the synthesis. The Acheson method is a direct reaction between high purity silicon and carbon black, and the pyrolysis method is a decomposition of polycarbonate silicon at temperatures between 1200 and 1500.

Silicon carbide ceramic performance characteristics

1. Excellent wear resistance

Silicon carbide ceramic wear resistance is very good, after a study determined that its wear resistance is equivalent to 266 times the manganese steel, equivalent to 1741 times the high chromium cast iron, so silicon carbide ceramic in the use of the process can greatly reduce the wear and tear of equipment, to reduce the frequency and cost of maintenance, we can save a lot of money, and silicon carbide ceramic is able to use more than ten years of continuous time.

2. high strength, high hardness, light weight

As a new material, silicon carbide ceramic use high strength, high hardness, light weight, so that, silicon carbide ceramic in use, installation and replacement will also be more convenient.

3. smooth inner wall, no blocking powder

Silicon carbide ceramic after high-temperature firing, the structure is relatively dense, smooth surface, the use of aesthetics will be better.

4. low cost

Silicon carbide ceramics in the manufacture of spending is relatively small, so we buy silicon carbide ceramics price spending is also relatively cheap, for normal families, can also save a lot of expenses.

Application of silicon carbide ceramics

The original application of silicon carbide is due to its super hard properties, can be prepared into a variety of grinding wheels, sand cloth, sandpaper and various abrasives, and therefore widely used in the machining industry. SiC ceramics have been widely used in petroleum, chemical, microelectronics, automotive, aerospace, aviation, paper making, laser, mining and atomic energy industries, and silicon carbide has been widely used in high temperature bearings, bulletproof plates, nozzles, high temperature corrosion resistant parts, and high temperature and high-frequency range of electronic equipment components and other fields.
