Products Description
Silicon Metal (Si) is a high-purity, crystalline elemental silicon primarily produced by smelting quartz (SiO₂) with carbon in an electric arc furnace. It is a critical raw material in various industries due to its semiconductor properties, heat resistance, and alloy-enhancing capabilities. With excellent conductivity and durability, silicon metal is indispensable in electronics, solar energy, and metallurgical applications.
