Abstract
A method for the manufacture of starting materials for fiber optical waveguides and the like from gas phase, wherein glass compositions are produced in a reaction zone in the presence of condensation nuclei being additionally introduced into said reaction zone and being used to increase the rate of glassforming and the rate of deposition of said glass composition being deposited on a solid surface as a soot or a powder. The nuclei can be added as particles of micron size to a carrier or reaction gas that is to be introduced into the reaction zone. The particles can be themselves produced immediately before the deposition zone in a reaction gas mixture which is subsequently introduced into the reaction zone.
