Abstract
A method for producing fine or ultra fine powder particles comprising mixing a metal alkoxide with a non-metallic hydride in an organic solvent, agitating the mixed solution, and then burning the mixed solution. The burning process comprises igniting the solution directly or burning the solution in situ. A self-sustaining flame will result. When the precursor solution burns, the metallic compound will be co-fired with the organic solvent. As a result, fine or ultra fine particles of mixed metal will burst from the flame, or thrust through the flame and be synthesized.

A method of forming powder particles, comprising:
- mixing a chelate, at least one non-metallic hydride and an organic solvent to form a mixed solution;
- and
- igniting the mixed solution directly to create a self-sustaining flame to produce powder particles.
A method of forming powder particles, comprising:
- mixing a chelate, at least one non-metallic hydride and an organic solvent to form a mixed solution;
- igniting the mixed solution directly to create a self-sustaining flame to produce powder particles;
- and
- utilizing a non-vacuum physical evaporation process to coat a surface of an object said evaporation process being defined as the bursting or thrusting of said powder particles through said self-sustaining flame onto said surface of said object to form an evenly distributed coating.
