ABSTRACT:
Very small and uniform metal oxide particles are produced by a process including the steps of ejecting a metal vapor-containing gas into a metal-oxidizing region through a nozzle and ejecting a molecular oxygen-containing gas into the metal-oxidizing region through another nozzle in such a manner that the streams of the metal vapor-containing gas and the molecular oxygen-containing gas are smashed into each other to produce a turbulent flow diffusing flame in which the metal vapor is oxidized into very small and uniform metal oxide particles.
