摘　　要：The phase transformation of 2MgO·2B 2O 3·MgCl 2·14H 2O H 2O sytem at boiling point has been studied.The final inversion product is 2MgO·B 2O 3·2H 2O,which was determined by chemical analysis and identified by infrared spectra and X ray diffractometry.The mechanism of dissolution and phase transformation has been proposed and discussed.The phase transformation of 2MgO·2B 2O 3·MgCl 2·14H 2O H 2O sytem at boiling point has been studied.The final inversion product is 2MgO·B 2O 3·2H 2O,which was determined by chemical analysis and identified by infrared spectra and X ray diffractometry.The mechanism of dissolution and phase transformation has been proposed and discussed.
