Abstract:
A seal formed between two parts that will remain gas tight in high temperature operating environments which experience frequent thermal cycling, which is particularly useful as an insulating joint in solid oxide fuel cells. A first metal part is attached to a reinforcing material. A glass forming material in the positioned in between the first metal part and the second part, and a seal is formed between the first metal part and the second part by heating the glass to a temperature suitable to melt the glass forming materials. The glass encapsulates and bonds at least a portion of the reinforcing material, thereby adding tremendous strength to the overall seal. A ceramic material may be added to the glass forming materials, to assist in forming an insulating barrier between the first metal part and the second part and to regulating the viscosity of the glass during the heating step.

Abstract:
Disclosed is a process for sealing component assembly to an electrical lighting device using induction heating. The assembly comprises the component, such as an electrode lead wire, and a solder glass perform. The process is useful, for example, in hermetically sealing and affixing lamp components, such as electrical lead wires and exhaust tubulation, to a low-pressure fluorescent discharge lamp envelope having phosphor coating already applied thereto. The present invention is particularly suitable for lamp envelopes made of borosilicate glass having a CTE from 0 to 300°C in the range of 30-45x10-7 °C-1.
Abstract:
Advanced implanted medical devices require long-lived, reliable power supplies. Lithium-ion batteries can be used to meet this need if they can be assured of maintaining a hermetic seal while implanted. The invention is a hermetic seal for a lithium-ion battery where the battery heater (5) is made of aluminum and the pin (1) is a conventional metal, such as platinum. The glass -to-metal seal utilizes low-temperature processable ALSG-32 glass, which has been demonstrated to bond to aluminum at temperatures below the melting point of aluminum and which has been demonstrated to exhibit excellent resistance to lithium battery electrolyte (9). ALSG32 is a high phosphate glass having about 6.0% B 2 O 3 , 40.0% P 2 O 5 , 15.0% Na 2 O, 18.0% K 2 O, 9.0% PbO, and 12.0% Al 2 O 3 , expressed in mole percent.

Abstract:
The invention concerns glass enamelling. The application of an enamel layer brings about a substantial modification in surface stresses of the glass sheet. Said modifications embrittle the sheet. In order to avoid such effects or at least to minimise them, the invention provides a treatment which consists in limiting the enamel composition curing. The inventive treatment is applicable to all uses wherein the enamelled part is subjected to mechanical loads, which is the case, for example, of enamelled zones whereon accessories are bonded.
Abstract:
The invention relates to a method for producing a composite part consisting of a component and a glass plate (10). According to said method, a body (1) formed by a semiconductor substrate is brought into contact with the glass plate (10) and an electric voltage is applied between the body (1) and the glass plate (10), said voltage been high enough to move the ions contained in the glass plate (10). Before the body (1) and the glass plate (10) are assembled, a connecting layer (8) containing silicon is applied on the body (1). Before the connection layer (8) is applied, at least one additional layer (2) is formed in or applied on the body (1) and doping agents are implanted on the additional layer (2).
