Abstract
A method of preparing an article made of a metallic material having its constituent elements includes the steps of furnishing at least one nonmetallic precursor compound, wherein all of the nonmetallic precursor compounds collectively include the constituent elements of the metallic material in their respective constituent-element proportions, and thereafter utilizing the nonmetallic precursor compound to produce a metallic injection molded brown article. The nonmetallic precursor compounds may be processed into the metallic material by first chemically reducing them to the metallic material, and then injection molding the metallic material, or first injection molding the nonmetallic precursor compounds and then chemically reducing them to the metallic material.
