Product Description
Silicon metal powder is a high-purity, ultra-fine-particle industrial silicon material, which is refined by crushing, grinding, grading and other processes of high-quality metallurgical-grade silicon (such as Si553, Si441, etc.). The silicon content is ≥98.0%, and the typical particle size range is 50 mesh to 800 mesh (micron or nanometer powder can be customized).The product is silver-gray powder with the characteristics of uniform particle size, large specific surface area, high activity and good fluidity.
Silicon metal powder can provide spherical silicon powder (plasma atomization method), irregular particles or nano silicon powder, which is suitable for special scenarios such as 3D printing, battery negative electrode materials, and ceramic reinforcement. Metallic silicon powder is widely used in new energy, chemical industry, metallurgy and advanced manufacturing fields, and is a key basic raw material for the synthesis of high-performance materials.
