Process For Injection Molding Sinterable Carbide Ceramic Materials

View page
US Patent:
42332567, Nov 11, 1980
Filed:
Dec 18, 1978
Appl. No.:
5/970702
Inventors:
Roger W. Ohnsorg - Niagara Falls NY
Assignee:
The Carborundum Company - Niagara Falls NY
International Classification:
C04B 3332
C04B 3564
US Classification:
264 44
Abstract:
Ceramic compositions that may be injection molded and subsequently sintered are described. A particulate ceramic material, such as silicon carbide, is coated with a mixture of thermoplastic resin and oils or waxes, and utilized as a feed material in an injection molding process. The molded product may subsequently be sintered at 2000. degree. C. to 2200. degree. C. to produce a hard, dense article.

US Patent:
58402217, Nov 24, 1998
Filed:
Dec 2, 1996
Appl. No.:
8/758715
Inventors:
Salavatore J. Calandra - Macedonia OH
Roger W. Ohnsorg - Grand Island NY
Assignee:
Saint-Gobain/Norton Industrial Ceramics Corporation - Worcester MA
International Classification:
C01B 3136
US Classification:
264 297
Abstract:
A process comprising the steps of: a) providing a fiber preform comprising a non-oxide ceramic fiber with at least one coating, the coating comprising a coating element selected from the group consisting of carbon, nitrogen, aluminum and titanium, and the fiber having a degradation temperature of between 1400. degree. C. and 1450. degree. C. , b) impregnating the preform with a slurry comprising silicon carbide particles and between 0. 1 wt % and 3 wt % added carbon c) providing a cover mix comprising: i) an alloy comprising a metallic infiltrant and the coating element, and ii) a resin, d) placing the cover mix on at least a portion of the surface of the porous silicon carbide body, e) heating the cover mix to a temperature between 1410. degree. C. and 1450. degree. C. to melt the alloy, and f) infiltrating the fiber preform with the melted alloy for a time period of between 15 minutes and 240 minutes, to produce a ceramic fiber reinforced ceramic composite.

US Patent:
54360420, Jul 25, 1995
Filed:
Mar 11, 1994
Appl. No.:
8/212536
Inventors:
Roger W. Ohnsorg - Grand Island NY
Salvatore J. Calandra - North Tonawanda NY
Assignee:
The Carborundum Company - Niagara Falls NY
International Classification:
F16B 500
US Classification:
428 346
Abstract:
This invention is directed to substantially strain-free, shaped, sintered ceramic fabric preform segments, to the production of the sintered preform segments from novel fixtured, shaped, green ceramic fabric preforms, and to sintered ceramic fiber-reinforced composite articles prepared from the sintered preforms and characterized in that the reinforcement phase is substantially free of mechanical strain, and the fiber in the fabric can exhibit a very small bending radius.
