摘要： 氟锆酸盐玻璃是一种性质优良的光学材料．本文系统地研究了PbF2、LiF、SrF2、HfF4、NaF和YF3等氯化物对氟锆酸盐玻璃的折射率nD、玻璃的形成能力和热膨胀系数α的影响．研究结果表明：PbF2和LiF能增大玻璃的折射率，SrF和HfF4能降低玻璃的折射率．根据玻璃的DTA曲线，确定了它们的最佳用量范围，在这一浓度范围内，玻璃的形成能力很好．

关键词: 氟锆酸盐玻璃, 折射率, 玻璃的形成能力, 热膨胀系数

Abstract: Fluorozirconate glass is a good kind of optical material. The paper systematically researchedthe effects of PbF4, LiF, SrF2, HU4, NaF and YF3 on the refractive index, glass-forming ability andthermal expansion coeffeciency of the fluorozirconate glass. The results show that PbF2 and LiFcan increase the refractive index of the glass, however, SrF2 and HfF4 can decrease the refractiveiudex. According the DTA of the glass, the optimum concentrations of these fluorides in whichthe glass has good glass-forming ability were determined.

Key words: fluorozirconate glass, refractive index, glass-forming ability, ability, thermal expasion
