Silicon powder is a fine-grained powder made up of silicon particles. It is used in a variety of industrial applications, including electronics, semiconductors, and solar panels.

Silicon powder can be produced through a variety of methods, including chemical vapor deposition, reduction of silicon dioxide with carbon in an electric furnace, and milling of silicon wafers.

Silicon powder is a light grey or dark grey powder with a high melting point and good thermal conductivity. It is a semiconductor with a wide bandgap, making it useful in high-temperature and high-power applications.
