Overview
Silicon Metal is a high-purity industrial product primarily composed of silicon (typically 96-99% purity), produced by reducing quartz with carbonaceous materials in electric arc furnaces. This essential material serves as a fundamental feedstock for numerous industries including aluminum alloys, chemicals, semiconductors, and solar photovoltaic manufacturing.
