20060150770, Jul 13, 2006

Filed:

Jan 12, 2005

Appl. No.:

11/035168

Inventors:

John Freim - Escondido CA, US
Clint Bickmore - Longmont CO, US

International Classification:

B22F 1/00
C22C 1/05

US Classification:

075343000, 075252000

Abstract:

The invention describes a procedure to make metal containing composite particles and composite particle suspensions. The procedure is versatile and can produce particles with a variety of particle sizes and compositions. For some applications the metal composite particles can provide the functionality of wholly metallic particles including configurations where the metal is located on the particle surface. Such metals have application in a wide variety of fields, including accomplishing electrochemical reduction and catalysis.

Abstract:

A process for producing nanoscale powders, and the powders so produced. The process comprises mixing an emulsion comprising all of the elements of the desired powder composition and a combustible fuel, and then combusting that emulsion to produce a powder. Powders with a median particle size of less than 50 nm have been made by this process. The process is suitable for the production of many types of powders, including particles and nanowhiskers of simple, doped, and polymetallic powders.
