Typical application:

  1. High purity silicon powder is widely used in high-purity semiconductor manufacturing. Due to the high melting point, thermal stability, rich resources and the improving technology of making high purity silicon, silicon integrated circuits and large-scale integrated circuits have been applied to various areas.
  2. In the silicone industry, silicon powder is the basis of synthetic materials and used in the production of silicone rubber, silicone resin to enhance their high temperature, electrical insulation, corrosion-resistant, and waterproof etc.
  3. It can also be used in the refractory industry. It acts as antioxidant additive, such as iron groove and iron ditch of iron smelting, mud water cannon, and containing silicon carbide castable ramming mixes to raise the temperature, resistant to wear and oxidation.
  4. In the metallurgical and foundry industry, it is acting as non-iron-based additives, silicon steel alloy agent to enhance the harden ability of steel. It can also be applied to certain metal reducing agent, such as a new type of ceramic alloy.
