DESCRIPTION
High purity silicon metal powder is a refined form of elemental silicon that has a purity level of 99.9% or higher. This high level of purity is achieved through advanced manufacturing processes, such as the use of high-purity raw materials and specialized purification techniques.
High purity silicon metal powder is a critical material for many applications in the semiconductor and photovoltaic industries, where even small impurities can adversely affect device performance. In these applications, the purity of the silicon metal powder is typically specified according to the amount of certain impurities, such as iron, aluminum, and other metals.
High purity silicon metal powder is also used in other applications that require high-purity materials, such as the production of optical fibers and certain types of ceramics.
