US Patent:

53343662, Aug 2, 1994
Filed:

Jan 7, 1993
Appl. No.:

8/001152
Inventors:

Anthony J. Perrotta - Monroeville PA
Randall B. Minnick - Lower Burrell PA
Assignee:

Aluminum Company of America - Pittsburgh PA
International Classification:

C01F 702
US Classification:

423625
Abstract:

A new transition alumina is made by heating substantially pure diaspore in a vacuum to an elevated temperature of about 300-1000. degree. C. The new transition alumina has increased surface area compared with alpha-alumina formed by heating diaspore in air.

US Patent:

54727340, Dec 5, 1995
Filed:

Sep 29, 1993
Appl. No.:

8/128860
Inventors:

Anthony J. Perrotta - Monroeville PA
Randall B. Minnick - Lower Burrell PA
Assignee:

Aluminum Company of America - Pittsburgh PA
International Classification:

B05D 138
US Classification:

427 2
Abstract:

A biocompatible coating is formed on an aluminum sheet surface by reacting a surface portion with an aqueous solution containing calcium hydroxide and a more soluble calcium salt to form a hydrocalumite first coating. The first coating is then reacted with a water-soluble phosphate to form a biocompatible coating comprising hydroxyapatite. The hydroxyapatite coating may be reacted with a water-soluble fluoride or fluorophosphate to form a fluorapatite coating.

US Patent:

59197242, Jul 6, 1999
Filed:

Mar 5, 1998
Appl. No.:

9/035360
Inventors:

Anthony J. Perrotta - Monroeville PA
Randall B. Minnick - Lower Burrell PA
Assignee:

Aluminum Company of America - Pittsburgh PA
International Classification:

B01J 3106
B01J 2714
B01J 2716
US Classification:

502159
Abstract:

A method for making catalyst particles having improved resistance to surface area loss through thermal degradation. The particles are preferably metal oxide particles and more preferably alumina hydrate particles having a surface area of at least about 150 m. sup. 2 /g. The particles are mixed with an organic monomer, preferably furfuryl alcohol. The monomer is polymerized to form polymer coated metal oxide particles. Thereafter, the polymer coated particles are treated with a phosphorus-containing acid or salt.
