Latest Patents
Phifer's latest patents include innovative sealing-glass compositions. One of her patents focuses on titanium sealing glasses and seals formed therefrom. This invention involves alkaline-earth lanthanoborate sealing-glass compositions containing CaO, La₂O₃, B₂O₃, TiO₂, and Al₂O₃ in various combinations. These compositions are designed to create hermetic glass-to-metal seals with titanium and titanium alloys, which exhibit high aqueous durability for applications that require exposure to moisture, water, or body fluids. Specific applications include forming glass-to-metal seals for lithium batteries and implanted biomedical devices such as batteries, pacemakers, defibrillators, and pumps.
Another patent by Phifer involves sealing glasses for titanium and titanium alloys. This invention presents barium lanthanoborate sealing-glass compositions comprising various combinations of boron oxide (B₂O₃), barium oxide (BaO), lanthanum oxide (La₂O₃), and at least one other oxide. These sealing-glass compositions are useful for forming hermetic glass-to-metal seals with titanium and titanium alloys, offering improved aqueous durability and favorable sealing characteristics. The compositions are designed to have coefficients of thermal expansion similar to those of titanium or titanium alloys, with sealing temperatures below 900°C, typically around 700-800°C. These compositions are particularly beneficial for components and devices that require prolonged exposure to moisture or water, as well as for implanted biomedical devices.
