摘要
配制 3Li2 O·B2 O3 - 2 0 %LiCl-H2 O过饱和溶液在 2 0± 0 1℃恒温水槽中静置。采用结晶动力学方法研究过饱和溶液的结晶过程 ,此过饱和溶液结晶后析出Li2 O·B2 O3 ·4H2 O一种固相 ,拟合给出结晶动力学方程 ,同时对结晶反应机理进行了探讨。
The 3Li 2O·B 2O 3-20%LiCl-H 2O supersaturated solution was prepared and kept in thermostat at 20±0 1℃.The crystallization processes of Li 2O·B 2O 3·4H 2O from above supersaturated solution were studied by kinetic method.The solid phases were characterized by XRD,IR-spectra and TG-DTG.The kinetic equation was fitted with experimental data by using a computer,and the crystallization reaction mechanism was proposed.
