Method Of Making A Ceramic Tube

View page
US Patent:
55079865, Apr 16, 1996
Filed:
Sep 16, 1994
Appl. No.:
8/308070
Inventors:
Sung S. Pak - Evington VA
Archie N. Tolley - Appomattox VA
Assignee:
The Babcock & Wilcox Company - New Orleans LA
International Classification:
B29C 5356
US Classification:
264 62
Abstract:
An improved method of making a ceramic tube includes preparing a tube from ceramic fibers with filament winding. The tube is impregnated with a pre-ceramic water soluble polymer solution. The impregnated tube is dried and heated to a temperature of about 500. degree. C. with the impregnating and heating steps being repeated.

View page
US Patent:
56701039, Sep 23, 1997
Filed:
Nov 21, 1995
Appl. No.:
8/561226
Inventors:
Sung S. Pak - Evington VA
Archie N. Tolley - Appomattox VA
Assignee:
The Babcock & Wilcox Company - New Orleans LA
International Classification:
C04B 3332
US Classification:
264 66
Abstract:
A method of making ceramic fibers from a water soluble pre-ceramic polymer solution by forming fibers from a water soluble pre-ceramic polymer solution, drying the formed fibers at a first temperature ranging between 600. degree. C. -750. degree. C. at a temperature heating rate of about 1. degree. C. per minute. Next, raising the first temperature to a second temperature ranging from 800. degree. C. -1000. degree. C. at about 5. degree. C. per minute, and increasing the second temperature to still a third temperature of about 1200. degree. C. at about 10. degree. C. per minute and holding at the third temperature for about 1 hour. Finally, the fibers are cooled to room temperature at a rate of about 5. degree. C. to 30. degree. C. per minute.

US Patent:
54378524, Aug 1, 1995
Filed:
May 13, 1993
Appl. No.:
8/061134
Inventors:
Sung S. Pak - Evington VA
Archie N. Tolley - Appomattox VA
Assignee:
The Babcock & Wilcox Company - New Orleans LA
International Classification:
C01F 1700
C01F 702
US Classification:
423263
Abstract:
A method of making water soluble pre-ceramic polymers includes heating hydrated metal salts above their melting points. A flow of air drives off water and most of the ligands. Polymerization occurs in the melt and the remaining side groups make the polymer soluble in water. Solubilization in water is accomplished by mixing the polymer with distilled water and heating the mixture at a temperature higher than about 60. degree. C. Thus prepared polymer solutions may be used to form fibers, films, and composite matrices.

Continuous Deposition Of Bridge Free Interfacial Coatings On Multifilamentary Ceramic Fiber Tows

US Patent:
57166714, Feb 10, 1998
Filed:
Jun 2, 1994
Appl. No.:
8/252809
Inventors:
Sung S. Pak - Chula Vista CA
Richard W. Goettler - Lynchburg VA
Archie N. Tolley - Appomattox VA
Assignee:
The Babcock & Wilcox Company - New Orleans LA
International Classification:
B05D 700
US Classification:
427214
Abstract:
A method for coating ceramic fibers such as Al. sub. 2 O. sub. 3 fibers includes immersing the Al. sub. 2 O. sub. 3 fibers in a polyelectrolyte solution. After the polyelectrolyte is allowed to adsorb on the fibers, the unabsorbed polyelectrolyte is washed from the fibers with a distilled water. The fibers are then deposited in an oxide solution such as SnO. sub. 2. The SnO. sub. 2 is allowed to adsorb on the fibers, and then the unabsorbed SnO. sub. 2 is washed from the fibers with the distilled water. The fibers are then sintered at a temperature ranging from 400. degree. C. to 1200. degree. C.
