We studied on glass-forming regions, thermal properties and water resistant test of lead oxide-free low melting glass based on bismuth oxide. We found the following results.(1)Bi_2O_3-B_2O_3-Li_2O, Bi_2O_3-B_2O_3-BaO, Bi_2O_3-B_2O_3-ZnO ternary systems have wide glass-forming regions.(2)The glass transition temperature (Tg) of Bi_2O_3-B_2O_3-X ternary glasses containing a 3rd component which are alkaline oxides, alkaline earth oxides, and intermediate oxides is 270 to 547℃. Increase of AI_2O_3 and TiO_2 in Bi_2O_3-B_2O_3-Al_2O_3 and Bi_2O_3-B_2O_3・TiO_2 ternary glasses hardly rises the Tg of these glasses.(3)The water resistance of Bi_2O_3-B_2O_3-ZnO, Bi_2O_3-B_2O_3-TiO_2 and Bi_2O_3-B_2O_3-Zr0_2 ternary glasses are nearly equal to that of 50SiO_2-50PbO(mol%) glass.We think that it has the possibility that as for the bismate glasses in this study, it is applied to some electronic devices from the above results.

研究了氧化铋基无铅低熔玻璃的玻璃形成区域、热性能和耐水性能。我们发现了以下结果。(1)Bi Bi_2O_3-B_2O_3-Li_2O、Bi_2O_3-B_2O_3-BaO、Bi_2O_3-B_2O_3-ZnO三元系统具有较宽的玻璃形成区。（2）含碱金属氧化物、碱土金属氧化物和中间氧化物的Bi_2O_3-B_2O_3-X三元玻璃的玻璃化转变温度（Tg）为270 ~ 547℃。Bi_2O_3-B_2O_3-Al_2O_3和Bi_2O_3-B_2O_3·TiO_2三元玻璃中Al_2O_3和TiO_2含量的增加对玻璃的Tg几乎没有影响。（3）Bi_2O_3-B_2O_3-ZnO、Bi_2O_3-B_2O_3-TiO_2和Bi_2O_3-B_2O_3-ZrO_2三元玻璃的耐水性与50SiO_2- 50 PbO（mol%）玻璃的耐水性相当，从以上结果我们认为，对于本研究的铋酸盐玻璃，有可能将其应用于某些电子器件。
