Products Description
Silicon metal (symbol: Si) is a non-ferrous material derived from quartz (SiO₂) through a high-temperature smelting process using carbon as a reducing agent in an electric arc furnace. It is a silver-gray, hard, and brittle crystalline metal used primarily in alloying, chemical, and semiconductor industries.
We supply metallurgical-grade and chemical-grade silicon metal, including standard and customized specifications for specific industrial applications.
