A process for the production of silicon comprising reacting a gaseous silicon compound of the formula SiH.sub.n X.sub.4-n, wherein X is halogen and n is 0 to 3, with aluminum in solid state. The resulting silicon can be highly pure and will have the particle size of the aluminum feed, making it especially useful for production of solar cells.
