Preceramic Compositions And Ceramic Products
US Patent:
4835207, May 30, 1989
Filed:
Nov 13, 1987
Appl. No.:
7/120102
Inventors:
John Semen - Baton Rouge LA
John J. Rogers - Baton Rouge LA
John J. Rogers - Baton Rouge LA
Assignee:
Ethyl Corporation - Richmond VA
International Classification:
C08K 334
US Classification:
524443
Abstract:
Low density SiC ceramics having improved bending and specific strengths are prepared by (A) intimately mixing about 50-85% by weight of SiC powder with about 15-50% by weight of a preceramic polysilazane binder, (B) pulverizing the mixture to form particles having a particle size smaller than 105 micrometers, (C) separating from those particles any particles having a particle size larger than about 105 micrometers, (D) molding the resultant composition having a particle size not larger than about 105 micrometers, and (E) pyrolyzing the molded composition in an inert atmosphere to a temperature of about 1200. degree. -1450. degree. C.
In a preferred embodiment of the invention, the preceramic binder is at least one polysilazane prepared by reacting an organodihalosilane with ammonia, treating the ammonolysis product with a basic catalyst which is capable of deprotonating an NH group that is adjacent to an SiH group, and quenching the resultant product with an electrophilic quenching reagent.

Process For Improving Strength Of Sic Ceramics
US Patent:
4845058, Jul 4, 1989
Filed:
Mar 4, 1988
Appl. No.:
7/164398
Inventors:
John J. Rogers - Baton Rouge LA
John Semen - Baton Rouge LA
John Semen - Baton Rouge LA
Assignee:
Ethyl Corporation - Richmond VA
International Classification:
C04B 3556
US Classification:
501 88
Abstract:
The strength of SiC ceramic parts derived from certain preceramic compositions is improved by (A) cooling the parts in an inert atmosphere to a temperature at least as low as about 800. degree. C. after preparing them by molding and pyrolyzing the preceramic compositions, (B) then heating them in air to about 1200. degree. -1300. degree. C. , and (C) keeping them in air at that temperature for at least about one hour before allowing them to cool. The preceramic compositions from which the ceramics are derived are mixtures of SiC powders and polysilazanes having an alkali metal content of 0-100 ppm and prepared by reacting an organodihalosilane with ammonia, treating the ammonolysis product with a basic catalyst which is capable of deprotonating an NH group that is adjacent to an SiH group, and quenching the resultant product with an electrophilic quenching reagent.
