DESCRIPTION
Silver gray silicon metal powder is a finely powdered form of elemental silicon that has a silver-gray color. This color is due to the highly reflective surface of the powder particles, which can give the appearance of a shiny metallic surface.
The properties of silver gray silicon metal powder are similar to other forms of silicon metal powder, with a high melting point, good thermal conductivity, and high electrical resistivity. It is commonly used in the production of semiconductors, alloys, and other industrial applications.
The production of silver gray silicon metal powder typically involves the reduction of high-purity silica with carbon in an electric arc furnace, followed by the grinding and milling of the resulting silicon metal to produce a fine powder. The particle size and distribution of the powder can be controlled through various milling and classification techniques.
