Abstract

A method for producing synthetic fused quartz is provided. The method includes evaporating a feedstock material which contains at least one polymerizable polyalkylsiloxane compound, and supplying the feedstock material vapor to a reaction zone, wherein the feedstock material vapor is converted by oxidation and/or by hydrolysis into SiO2 particles. The feedstock material vapor is passed through a membrane filter as a cleaning device to reduce the formation of gel, which is typically associated with the production of synthetic fused quartz.
