The results show that the system is complicated with four equilibrium solid phases CdCl2·H2O, 8CdCl2·LaCl3·16H2O(8∶1 type), 4CdCl2·LaCl3·12H2O(4∶1 type) and LaCl3·7H2O, respectively. The two new compounds 8CdCl2·LaCl3·16H2O(8∶1 type) and 4CdCl2·LaCl3·12H2O(4∶1 type) are congruently soluble in ～9.7%HCl H2O medium and have not yet been reported in literatures. Both compounds have been prepared from the system and have been characterized by XRD, TG DTG and DSC.展开更多
