Abstract

A method for passivating metal-containing powder condensate and the resulting passivated metal. A metal-containing powder condensate comprising at least one metal is combined with at least one binder and at least one solvent to form a slurry, wherein the solvent only partially dissolves the powder-binder mixture. The resulting slurry is dried to remove excess solvent, forming a passivated metal-binder solid cake.
