Method Of Forming Hybrid Arc Tubes

View page
US Patent:
49991450, Mar 12, 1991
Filed:
Dec 15, 1989
Appl. No.:
7/451406
Inventors:

Assignee:
GTE Laboratories Incorporated - Waltham MA
International Classification:
C04B 3510
US Classification:
264 60
Abstract:
Disclosed is a method for forming alumina arc tubes of complex shapes. The method comprises molding alumina powders with different shrinkage rates into a green body. The green body is prefired to remove binders in the green body and then sintered. The resulting arc tube has an inner diameter that is smallest where the highest shrinkage powder was molded and an inner diameter that is greatest where the lowest shrinkage powder was used.

US Patent:
57258279, Mar 10, 1998
Filed:
Mar 28, 1995
Appl. No.:
8/415139
Inventors:
William H. Rhodes - Lexington MA
Alfred E. Feuersanger - Framingham MA
Rodrigue Thibodeau - Marblehead MA
Assignee:
Osram Sylvania Inc. - Danvers MA
International Classification:
C04B 3510
C04B 35117
US Classification:
264614
Abstract:
Alumina arc tube sealing members including a highly pure, fine alumina doped with yttrium oxide, and magnesium oxide. The sealing members are used in the formation of sintered hermetic seals to a green, prefired, or fully sintered translucent alumina arc tube and niobium electrical feedthrough assemblies with or without the use of sealing frits or brazing alloys.
