Abstract

A method for the production of silicon oxide particles includes the pyrolysis of a molecular stream with a silicon compound precursor, an oxygen source and a radiation absorbing gas. The pyrolysis is driven by a light beam such as an infrared laser beam. The method can be used in the production of nanoscale particles including highly uniform nanoscale particles.
