ABSTRACT:
A metal or an alloy thereof, or a ceramic that has a liquid phase is introduced in the form of a rod or a wire or as a liquid stream into the apex formed by a plurality of converging plasma jets. Atomization takes place and upon controlled cooling good quality spheroidal powders are obtained whose size varies generally between about 10 and 300 .mu.m.
