In this study, V_2O_5, ZnO, BaO, TeO_2, P_2O_5 were chosen for development of low melting lead-free sealing glasses. The glass forming region, glasss transition temperature, softening temperature, thermal stability, thermal expansion property, and X-ray properties were investigated in detail in the ternary (V_2O_5-ZnO-BaO) and quaternary (V_2O_5-ZnO-BaO-TeO_2 or P_2O_5) systems. It was exhibited that the lead-free glasses had good sealing property in some tests with a flat fluorescence lamp. Hence, the sealing properties of these lead-free glasses were showed an excellent performance as a substitute for the commercial lead sealing glass.}, pages = {79--86}, title = {鉛フリー低融点ガラスの実用化に向けた研究開発}, volume = {47}, year = {2005} }
