A process for producing a silicon-SiC composite powder is provided. A gas stream I containing SiH, SiHand/or SiHand at least one hydrocarbon of ethene and acetylene and a coaxial gas stream II containing hydrogen are fed into a hot wall reactor. The gas stream II forms the jacket stream with respect to the gas stream I. At least the gas stream I is reacted at a temperature of 900&#xb0; C. to 1100&#xb0; C. and subsequently at the outlet of the hot wall reactor the reaction mixture is cooled or allowed to cool and the pulverulent reaction product is separated from the gaseous materials.
