Development of a low temperature sealing phosphate glass

Abstract

"Phosphate glass compositions were evaluated in this work. The general compositions were P₂O₅-Al₂O₃-Fe₂O₃-CuO-PbO-ZnO-Li₂O and P₂O₅-V₂O₅-Al₂O₃-B₂O₃-PbO-Li₂O-Na₂O. These glasses were investigated for the purpose of identifying phosphate glasses whose thermal expansion, dilatometer softening temperature and chemical durability are suitable for sealing to medium expansion (α=110-125x10^-7/°C) and low expansion materials (α=80-90x10^-7/°C). Potential compositions has been identified for commercial application. The effect of different additives such as Al₂O₃, B₂O₃, PbO, ZnO, alkaline earth and transition oxides on the properties of phosphate glasses were also investigated"--Abstract, page 1.
