The combustion chamber is provided with a gas inlet and a gas outlet arranged at opposite ends of the combustion chamber, which widens from the inlet to the outlet. The gas flow is produced by a central nozzle for the silicon compound, a first concentric ring-shaped nozzle for the oxidizer, and a second concentric ring-shaped nozzle for the fuel. The process is characterized by a ratio of areas of ring gaps of the ring-shaped nozzles of from 1:4 to 1:6.1. The apparatus for the process is also part of the invention.
