US Patent:

47132337, Dec 15, 1987

Filed:

Sep 24, 1986

Appl. No.:

6/910929

Inventors:

Gary B. Marsh - Pittstown NJ
Anthony J. Fanelli - Rockaway NJ
John N. Armor - Morris Plains NJ
Patrick M. Zambri - Montclair NJ

Assignee:

Allied Corporation - Morris Township, Morris County NJ

International Classification:

C01G 2502

US Classification:

423608

Abstract:

Inorganic metal oxides having high surface area and pore volume are prepared by spray drying. The admixture which is spray dried to yield the metal oxides is produced from reactants comprising at least one hydrolyzable metal compound, a sufficient amount of water to at least partially hydrolyze the metal compound and an organic solvent. The admixture is supplied as a plurality of droplets to a reaction zone operated under conditions of temperature and pressure below the critical temperature and pressure of the reactants but sufficient to produce a product comprising metal oxide powders and a gas comprising organic solvent vapors. The powders are separated from the gas in a known fashion and collected. Spray drying of non-aqueous systems unexpectedly produces metal oxides having properties generally intermediate conventionally produced oxides and aerogels.

US Patent:

Filed:

Oct 20, 1993

Appl. No.:

8/139498

Inventors:

Ronald P. Rohrbach - Flemington NJ
Julie R. Schollmeyer - Des Plains IL
Anthony J. Fanelli - Rockaway NJ

Assignee:

Alliedsignal Inc.

International Classification:

B29C 3900

US Classification:

264122

Abstract:

A gel-forming composition is used in a process for molding a ceramic composition. The gel-forming composition, such as agar, is improved with a gel-enhancing agent, e. g. polyethyleneimine. As a result, the gel-forming composition improves the ceramic molding process and/or the ceramic product formed therefrom.

Assignee:

Allied Signal Inc. - Morristown NJ

International Classification:

C08L 512
B09C 3900

US Classification:

524 27

Abstract:

Novel gel-forming compositions are used in a process for molding ceramic compositions. Gel-forming compositions, such as agar, are improved with a gel-enhancing agent, e. g. polyethyleneimine. The novel gel-forming compositions improved the ceramic molding process and/or the ceramic products formed therefrom.

Filed:

Jun 25, 1991

Appl. No.:

7/720548

Assignee:

Allied-Signal, Inc. - Morristownship, Moris County NJ

International Classification:

C04B 3548

US Classification:

501105

Abstract:

A ceramic element of a zirconia oxygen sensor is shaped from a powder mixture. The mixture, comprising a ceramic powder having an average particle size less than or equal to 1 micrometer, a gel-forming material and a gel forming material solvent, is molded at a temperature and pressure sufficient to produce the ceramic element having a density of at least 5. 5 g/cm. sup. 3.
