DESCRIPTION
Silicon metal powder is a finely powdered form of elemental silicon, which is a chemical element with the symbol Si and atomic number 14. It is a grey, metallic-looking powder with a high melting point and good thermal conductivity. Silicon metal powder is widely used in various industries, including the production of semiconductors, solar cells, alloys, and refractories. The production of silicon metal powder typically involves the reduction of high-purity silica with carbon in an electric arc furnace. The resulting silicon metal is then ground into a powder with a controlled particle size distribution.
