摘要
测定了氟铍酸三甘肽（ＴＧＦＢ）晶体在０～３０ｗｔ－％的乙二醇，水混合溶剂中，温度区间为２５～５０℃的溶解度和过饱和度曲线，确定了生长亚稳区范围，拟合出了溶解度随温度、乙二醇浓度变化的经验方程式为Ｓ＝（１─０．８６７ｍ）×３．８２×１０￣（－１３）Ｔ￣（５．７６）─４０．０ｍ，并讨论了溶液的稳定性。以混合溶剂代替纯水作溶剂，拓宽了溶液的亚稳区，有望改善晶体生长条件，缩短生长周期。
The solubilities of triglycine fluoroberyllate (TGFB)crystal in ethylene glycol(0 30%) water solvents have been determined in the temperature range 25 50℃,and an empirical formula S=(1 0. 867m) × 3. 82× 10￣(-13)T￣(5.65)─40.0m has been obtained by curve fitting,The supersaturation curve and metastable region of TGFB solution are given. The metastable regions of TGFB solutions in ethylene glycol-water solvents are wider than that in pure water,so that it can be probably hoped to improve the condition of crystal growth.
