Silicon powder is silicon that has been ground into a finely powdered dust. Depending on the purity of the silicon powder, it can be used for many purposes. It can be sintered, alloyed with metals to harden the mixture, made into microchips, used as a reactant in silicon compounds, or used in glass plasma deposition. Powdered silicon usually is made without any additional elements, but it can be mixed with elements such as carbon or oxygen to create different powders.
