Silicon Metal Powder for Silicone Production, Aluminum Alloy and Metallurgical Applications
Silicon Metal Powder is a high purity industrial material produced by crushing, grinding, and classifying silicon metal into fine particles with controlled size distribution. Due to its high silicon content, low impurity levels, and excellent chemical reactivity, silicon metal powder is widely used in silicone production, aluminum alloy manufacturing, metallurgical applications, refractory materials, and advanced industrial processes.
Compared with lump silicon metal, silicon metal powder provides better mixing performance and faster reaction efficiency, making it suitable for industries requiring precise silicon addition and consistent material performance. ZhenAn supplies high purity silicon metal powder with stable chemical composition, customized particle sizes, and reliable quality control for global industrial customers.
