Practical application study of lead oxide-free low melting glass based on bismuth oxide

我们对玻璃形成的区域、热性能和耐水性进行了测试，对铅氧化物-自由低熔融玻璃进行了研究，并对铋氧化物进行了研究。我们找到了以下的结果。（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）Bi_2O_3-B_2O_3-X交替玻璃含有碱性氧化物、碱性地球氧化物和中氧化物的第三种成分的玻璃过渡温度（Tg）为270 - 547℃。Increase of AI_2 O_3 and TiO_2 in Bi_2 O_3-B_2 O_3-Al_2 O_3 and Bi_2 O_3-B_2 O_3·TiO_2 ternary glasses hardly rises the Tg of these glasses。（3）Bi_2O_3-B_2O_3-ZnO、Bi_2O_3-B_2O_3-TiO_2和Bi_2O_3-B_2O_3-Zr0_2备用玻璃接近等于50SiO_2- 50 PbO（mol%）玻璃。我们认为它具有本研究中的双相玻璃的可能性，它是从上一个结果中应用到一些电子器件的。

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.
