1. A process for producing essentially spherical metallic powders particles, said process comprising:

  • (a) mechanically agglomerating a mixture comprising powders, wherein said powders are selected from the group consisting of metals, metal alloys, metal-ceramic composites, ceramics, and wherein at least one of said powders is a relatively ductile and/or malleable metal;

    (b) entraining the resulting mechanically agglomerated powder particles in a carrier gas and passing said mechanically agglomerated particles through a high temperature zone at a temperature above the melting point of the lowest melting component of said mixture to melt at least about 50% by weight of said mechanically agglomerated particles and form essentially spherical powder particles of said melted portion; and

    (c) resolidifying the resulting high temperature treated material.
