| Abstract: | The Li 2O·nB 2O 3(n=4,5)-20%LiCl-H 2O supersaturated solution were prepared and kept in thermotat at 20±0 1℃.The crystallization processes of LiB 5O 8·5H 2O from above supersaturated solution have been studied by kinetic method.The solid phases were characterized by XRD,IR-spectra and Chemical analysis.The crystallization kinetic equation of these compounds were fitted with experimental data by computer,and the crystallization reaction mechanism has been proposed. |
