摘　　要：本实验确定了SrO-La2O3-P2O5三元系统玻璃的形成区域,并研究了组成的摩尔分数变化对xSrO-10La2O3-(90-x)P2O5(5≤x≤30)三元系统玻璃结构和性能的影响。通过红外光谱、折射率与透过率分析、热膨胀曲线测定以及耐水性测试等方法对其结构和性能进行了分析。结果表明,随着SrO摩尔分数的增加,玻璃折射率增长趋势明显,阿贝数变化较小,密度先减小后增加;透过率在可见光范围内逐渐增加;转变温度下降,热膨胀系数增加,耐水失重率先上升后下降。The glass formation regions of SrO-La2O3-P2O5 ternary system were determined,and the effects of molar composition on the structures and properties of xSrO-10La2O3-(90-x)P2O5(5≤x≤30)ternary system glasses were studied.The structures and properties were analyzed by infrared spectroscopy,refractive index and transmittance data,high temperature thermal-expansion curves and water resistance tests,etc.The results indicated that the refractive index of glasses obviously increased,and the change of Abbe number was tiny.The density initially decreased and then increased with the increasing of SrO content.The transmittance of glasses gradually increased in the visible range.With the increasing of SrO content,the thermal expansion coefficient of glasses increased,and the transition temperature decreased.The weightlessness of glasses initially increased and then decreased.
