Filed:

Feb 11, 2002

Appl. No.:

09/786999

Inventors:

James H. Brewster - Rio Rancho NM
David E. Dericotte - Albuquerque NM
Mark J. Hampden-Smith - Albuquerque NM
Toivo T. Kodas - Albuquerque NM
Quint H. Powell - Albuquerque NM

Assignee:

Superior MicroPowders LLC - Albuquerque NM

International Classification:

B22F 906

US Classification:

75331, 75355, 75370, 264 5, 264 9, 264 12

Abstract:

A process for making particles, the process including generating an aerosol stream which includes droplets of a precursor liquid dispersed in a carrier gas, the precursor liquid including a liquid vehicle and a precursor material, separating the precursor liquid into two portions during the generating step, a first portion exiting the generator in the droplets of the aerosol stream and a second portion exiting as effluent at least a portion of which is recycled to the generator, and also during the generating step adding additional liquid vehicle to at least one of the carrier gas supply, the precursor liquid supply, and the aerosol generator, to at least partially compensate for the tendency of the precursor liquid to become more concentrated in the precursor material over time, and then removing at least a portion of the liquid vehicle from the droplets and forming particles in the aerosol stream.

502180, 502182, 502300, 429 40, 429 41, 429 42, 429 43, 429 44

Abstract:

Electrocatalyst powders and methods for producing electrocatalyst powders, such as carbon composite electrocatalyst powders. The powders have a well-controlled microstructure and morphology. The method includes forming the particles from an aerosol of precursors by heating the aerosol to a relatively low temperature, such as not greater than about 400 C.
