ABSTRACT:
A process for preparing finely divided silica by reaction of gaseous or vaporizable silicon compounds in a mixture with gases forming water on combustion with air or oxygen in a flame includes producing discharges of gas in the combustion chamber by means of at least one gas gun. The apparatus for carrying out this process has applied to the outside of the combustion chamber wall at least one gas gun which produces a discharge of gas via an opening in the combustion chamber wall, preferably in conjunction with a nozzle on the inside of the combustion chamber wall.
