摘要: 用动力学方法对Li2O·nB2O3-20%LiCl-H2O体系(n=1,2,3)20℃过饱和溶液结晶过程进行研究,结果表明每一种溶液只析出一种固相,Li2O∶B2O3=1∶1、1∶2和1∶3的氯化锂溶液分别结晶出Li2O·B2O3·4H2O, Li2O·2B2O3·3H2O和Li2O·5B2O3·10H2O,拟合并给出结晶动力学方程,同时对这三种固相的结晶反应机理进行了探讨。

Abstract: The Li2O·nB2O3(n=1,2,3) supersaturated solution of Li2O·nB2O3-20%LiCl-H2O system were prepared and kept at 20℃. The crystallization of different hydrated Li-borates from the solution has been studied by the kinetic method. There were three solid phases, Li2O·B2O3·4H2O, Li2O·2B2O3·3H2O and Li2O·5B2O3·10H2O in the system. The kinetic equation of crystallization of these compounds were fitted by computer. The crystallization reaction mechanism has been suggested.
