A lead-tellurium-lithium-titanium-oxide glass composition is useful as a component of a conductive silver paste. Especially useful are P-containing and V-containing lead-tellurium-lithium-titanium-oxide glass composition. Conductive silver via paste comprising particulate conductive silver and any of the lead-tellurium-lithium-titanium-oxide glass compositions of the invention can be used in providing the metallization of the holes in the silicon wafers of MWT solar cells. The result is a metallic electrically conductive via between the collector lines on the front side and the emitter electrode on the back-side of the solar cell. The paste can also be used to form the collector lines on the front-side of the solar cell and the emitter electrode on the back-side of the solar cell.

An antimony-free glass suitable for use in a frit for producing a hermetically sealed glass package is described. The hermetically sealed glass package, such as an OLED display device, is manufactured by providing a first glass substrate plate and a second glass substrate plate and depositing the antimony-free frit onto the first substrate plate. OLEDs may be deposited on the second glass substrate plate. An irradiation source (e.g., laser, infrared light) is then used to heat the frit which melts and forms a hermetic seal that connects the first glass substrate plate to the second glass substrate plate and also protects the OLEDs. The antimony-free glass has excellent aqueous durability, good flow, low glass transition temperature and low coefficient of thermal expansion.

A dissolvable glass projectile for a firearm is molded from dissolvable glass for the ammunitions and firearms industry. The dissolvable glass projectile may be molded into different sizes or geometry based on firearm and user preference. A mixture of chemicals components are heated and melted and then poured into a mold and is allowed to cool to a solid that can be handled.

A borate bioactive glass is described, and may be used in the form of particles in an acidic mixture to form a borate bioactive glass paste. The borate bioactive glass paste may be used for the restoration of dentin and enamel on a tooth surface by the precipitation of calcium phosphate. The borate bioactive glass may also be used as a bone grafting material.
