ABSTRACT:
A method and apparatus for processing metal bearing gases involves generating a toroidal plasma in a plasma chamber. A metal bearing gas is introduced into the plasma chamber to react with the toroidal plasma. The interaction between the toroidal plasma and the metal bearing gas produces at least one of a metallic material, a metal oxide material or a metal nitride material.
