Preparation of high-purity semiconductors from metallic silicon: Modern large-scale integrated circuits are almost all made of high-purity metallic silicon. High-purity metallic silicon is the main raw material for the production of optical fibers. Metallic silicon has become a basic pillar industry in the information age.
Metallic silicon made of alloy: Metallic silicon aluminum alloy is a highly used silicon alloy. Silicon-aluminum alloy is a strong composite deoxidizer. In the steelmaking process, it can improve the utilization rate of deoxidizer, replace pure aluminum, purify molten steel, and improve the quality of steel. Silicon-aluminum alloy has low density, low thermal expansion coefficient, good casting performance and wear resistance. The cast alloy casting has high impact resistance, high pressure and high density, which can extend the service life.
