"The goal of the research described in this thesis was to develop and characterize novel sealing glasses that could be used for low temperature hermetic seals in glass and ceramic packages. Initially, glasses in the SnO-V2O5-P2O5 ternary were examined. In order to understand this ternary better, glasses in the SnO-P2O5 binary were examined. A dependence of the properties of tin metaphosphate glasses on processing conditions was discovered. The effect of fluorine in SnO-P2O5 was studied briefly. This research is described in section 1 .
The ZnO-P2O5-V2O5 ternary was studied and the glass forming region was found. P2O5 reduced the durability of these ternary glasses, and so glasses from the ZnO-V2O5-TeO2 ternary were examined next. The effects of adding B2O3 to specific ZnO-V2O5-P2O5 and ZnO-V2O5-TeO2 glasses were determined. Section 2 describes the structures and properties of SnO-V2O5-P2O5, ZnO-V2O5-P2O5, and ZnO-V2O5-TeO2 glasses. In addition, powder processing techniques and experiments with various low expansion fillers used to reduce thermal expansion coefficient are described"--Abstract, page iii.
