ABSTRACT:
A plasma method and apparatus produce oxide particles having average diameters determined by adjustment of process conditions. Feed material is fed into a dual chamber reaction zone in which a plasma environment is established to cause the feed material to be vaporized. Subsequently, effluent containing the vaporized feed from the reaction zone is passed into a quenching zone where it is subjected to a quenching medium, the volume, velocity and direction of which are adjustable to determine output particle size characteristics. Feed material may be an oxide per se or one which forms an oxide in situ through reduction and/or oxidation.
