Abstract

In atomizing a body of molten material having elevated melting point by directing the molten body as a stream into an atomization zone and directing a stream of atomizing gas into said stream to atomize and disperse it, the orifice from which the gas is delivered is positioned closely proximate the surface of the stream to be atomized, e.g. less than 0.45 inches way. A large percentage of fine particles is thereby produced. In an embodiment gas at high pressure enters plenum chamber 20 through conduit 30, emerges from annular gas orifice 22 to impinge on the stream of molten metal descending through tube 12 and emerging from the end 16. <IMAGE>
