Abstract

Method of manufacturing metal spheres of unified shape and size, characterized in that it comprises the operations of melting a supply material in the substantial absence of oxygen to form molten globules at one point, directing a flow of a non-oxidizing inert gas towards said point against the referred globules to atomize them in drops and to drive these from said point to a chamber in which they cool and solidify in the form of particles.
