Prealloyed Catalyst For Growing Silicon Carbide Whiskers
view source
US Patent:

47895373, Dec 6, 1988
Filed:

Jun 25, 1987
Appl. No.:

7/068796
Inventors:

Peter D. Shalek - Los Alamos NM
Joel D. Katz - Niagara Falls NY
George F. Hurley - Los Alamos NM
Assignee:

The United States of America as represented by the United States
Department of Energy - Washington DC
International Classification:

C01B 3136
US Classification:

423346
Abstract:

A prealloyed metal catalyst is used to grow silicon carbide whiskers, especially in the. beta. form. Pretreating the metal particles to increase the weight percentages of carbon or silicon or both carbon and silicon allows whisker growth to begin immediately upon reaching growth temperature.

US Patent:

47029013, Oct 27, 1987
Filed:

Mar 12, 1986
Appl. No.:

6/839302
Inventors:

Peter D. Shalek - Los Alamos NM
Assignee:

The United States of America as represented by the United States
Department of Energy - Washington DC
International Classification:

C01B 3186
US Classification:

423346
Abstract:

A method of growing silicon carbide whiskers, especially in the. beta. form, using a heating schedule wherein the temperature of the atmosphere in the growth zone of a furnace is first heated to or beyond the growth temperature and then is cooled to or below the growth temperature to induce nucleation of whiskers at catalyst sites at a desired point in time which results in the selection.
