Abstract

A metal oxide powder includes a powder feed material structured and arranged to form molten droplets when melted in a plasma stream. The molten droplets are structured and arranged to form frozen spherical droplets under free-fall conditions such that said molten droplets have ample time for complete in-flight solidification before reaching a collection chamber.
