A process of producing high-purity silicon includes providing silicon-containing powder, feeding the silicon-containing powder into a gas stream, where the gas has a temperature sufficiently high to convert particles of metallic silicon from a solid state into a liquid and/or gaseous state, collecting and, optionally, condensing the liquid and/or gaseous silicon formed, and cooling the collected liquid and/or condensed silicon in a casting mold, |
