Abstract

Process for providing silicon compounds from silicon dioxide compound, preferably from sand, having the following steps: a) introducing the silicon dioxide compound into a combustion zone, b) heating the combustion zone together with the silicon dioxide compound, c) conversion of silicon dioxide from the silicon dioxide compound into silicon (Si2), wherein a reducing agent is fed in order to remove the oxygen from the silicon dioxide, d) injecting a gaseous reaction partner in order to produce the silicon compound from the silicon (Si2).
