摘要
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, 8CdCl(2) (.) LaCl3 (.) 16H(2)O(8:1 type), 4CdCl(2) (.) LaCl3 (.) 12H(2)O(4:1 type) and LaCl3 (.) 7H(2)O, respectively. The two new compounds 8CdCl(2) (.) LaCl3 (.) 16H(2)O(8:1 type) and 4CdCl(2) (.) LaCl3 (.) 12H(2)O(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.
