| Abstract: The equilibrium solubility of the LaCl3-CdCl2-(9.7%)HCl-H2O quaternary system at 298K was determined and the phase diagram was constructed. 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 com-pounds have been prepared from the system and have been characterized by XRD， TG-DTG and DSC. | |
