Mill additions are disclosed which lower the CTE of, and are compatible with, tin-phosphorus oxyfluoride glasses. The sealing materials provide fusion-type seals having a CTE not over about 110×10-7/°C. and a sealing temperature not over about 350°C. Also disclosed is a family of glass compositions in the tin-phosphorus oxyfluoride system that exhibit very low glass transition temperatures and coefficients of thermal expansion not over about 160×10-7/°C. (25°-150°C.). In addition to the four basic elements, the glasses contain up to 11% Nb, and may addit...
A fusion sealing material composed of a tin-phosphorus oxyfluoride glass having a low transition temperature and a mill addition selected from the group consisting of Invar, molybdenum, tungsten, lead orthophosphate, magnesium pyrophosphate, a magnesium pyrophosphate with at least a portion of the magnesium ions replaced by at least one cation selected from the group composed of cobalt, arsenic, zinc, iron, aluminum and zirconium, and a crystallized phosphate glass composed essentially of P2O5 and one or more cations selected from the group composed of m...
