Abstract
A process for preparing a particulate metal oxide of small particle size wherein a combustible organometallic compound alone or in admixture with a combustible organic liquid carrier is introduced into a combustion zone and combusted in a combustion supporting gas to produce particles of metal oxide, the combustion being carried out under reaction conditions so as to effect calcination of the metal oxide particles prior to condensation of the particles in the bulk phase.
