Product Specification
Silicon Metal
Silicon metal is a high-purity elemental silicon produced by reducing quartz sand with carbon in an electric arc furnace. It is a key raw material for the aluminum, chemical, and semiconductor industries.
Applications
- Aluminum alloy production (primary deoxidizer)
- Chemical industry: silicone polymers and resins
- Semiconductor and photovoltaic solar cell production
- Manufacture of organosilicon compounds

Polycrystalline Silicon
Polycrystalline silicon (polysilicon) is a high-purity form of silicon consisting of multiple small silicon crystals. It is produced by the chemical vapor deposition (CVD) of trichlorosilane or silane, and serves as the primary feedstock for solar-grade and electronic-grade silicon wafer production.
Applications
- Solar photovoltaic (PV) wafer and cell manufacturing
- Semiconductor wafer production for integrated circuits
- High-purity silicon ingot casting for electronics
- Raw material for monocrystalline silicon pulling (Czochralski process)
