摘要
用传统熔体冷却方法制得B2O3-B aO-ZnO三元系统玻璃,考察了该系统玻璃的形成规律,并且探索了该系统玻璃的组成与性能之间的关系。结果表明:该系统玻璃的形成范围较宽,但B2O3的引入摩尔分数最高不能超过75%,最低不能少于25%。B2O3的含量过高,熔体冷却时容易分相,而B2O3的含量过低时,则熔体在冷却时容易结晶。获得玻璃的线胀系数在(6~10)×10-6K-1之间;转变温度在530~580℃之间;室温下电阻率在(2~5)×1010Ω·m之间;密度值较大。
The glass in the trinal system of B2O3-BaO-ZnO was prepared by a conuentional melt-cooling method.Its formation rule and relationship between the composition and properties were investigated.The results show that the additions of B2O3 should be limited in 25mol%~75mol%.The obtained glass has a larger density with a thermal expansion coefficient (6~10)×10-6K-1,transition temperature 530~580℃and resistivity at room temperature (2~5)×1010Ω·m.
