DESCRIPTION
High purity silicon metal powder is a type of powder that consists of small particles of pure silicon metal, typically with a purity level of 99.9% or higher. This powder is commonly used in a variety of industrial applications, including the production of semiconductors, solar cells, and other electronic components.
High purity silicon metal powder is made by reducing silicon dioxide with a reducing agent such as carbon or hydrogen, which produces pure silicon metal in the form of a powder. The powder is then carefully processed and purified to remove any impurities, resulting in a high purity product.
