摘　　要：４８ＺｒＦ４－２４ＢａＦ２－８ＡｌＦ３－２０ＲＦ（ＲＦ＝ＬｉＦ－ＮａＦ和ＮａＦ－ＫＦ）玻璃中引入不同比例的碱金属离子。利用ＤＴＡ研究玻璃的成玻性，并测定玻璃的化学稳定性和折射率。讨论了各理化性能的混碱效应。结果表明，混碱氟锆酸盐玻璃的成玻性和化学稳定性均优于单碱玻璃。当ＲＦ为ＬｉＦ－ＮａＦ且ＬｉＦ：ＮａＦ为１：３时有最佳的成玻能力，ＬｉＦ：ＮａＦ为１：１时玻璃有最好的化学稳定性。Alkali ions with defferent ratio were added to 48ZrF 4-24BaF 2-8AlF 3-20RF(RF=LiF-NaF and NaF-KF) glass. The glass formation tendency has been investigated by DTA. Chemical durability, refractive indices were measured. The effect of mixed alkali on physical and chemical properties was discussed.The results show that the glass formation tendency and chemical durability of glass with mixed alkali ions are better than that of glass with single alkali ion. The best glass formation tendency of 8ZrF 4-24BaF 2-8AlF 3-20RF glass can be achieved when LiF:NaF is 3:1 and the best chemical durability can be obtained when LiF:NaF is 1:1.
