Description:
Silicon metal is also called industrial silicon, dark gray, high melting point and resistivity, good heat resistance and good anti-oxidation effect.
Application:
1. Used in aluminum: an additive to aluminum alloys, silicon is used to increase the fluidity and tenacity of Aluminum and its alloys, which enjoy good castability and weldability accordingly.
2. Used in organic chemicals: silicon metal is used in manufacturing a number of sorts of silicones, resins, and lubricants.
3. Used in electronic parts: silicon metal is used in producing monocrystalline and polycrystalline silicon of high purity for electronic parts, such as semi conductors, etc.
