Product Description
Silicon metal powder is an ultra-fine, high-purity industrial silicon product derived from premium metallurgical-grade silicon (e.g., Si553, Si441) through precise crushing, grinding, and airflow classification processes. This lustrous silver-gray silicon metal powder features uniform particle distribution, exceptionally large specific surface area, outstanding chemical reactivity, and superior flowability, making silicon metal powder the preferred high-performance material in advanced metallurgical, chemical, and new-energy applications.
Silicon metal powder is the top-choice deoxidizer for ultra-clean steel, Silicon metal powder significantly boosts magnesium smelting efficiency, Silicon metal powder enhances aluminum alloys and polysilicon production, Silicon metal powder is the core material for organosilicon monomers and high-capacity lithium battery anodes, making Silicon metal powder the indispensable high-activity silicon source in new-energy and high-tech industries.
