摘要：
The equilibrium solubility of one CsCl-YCl3-H2O ternary section Of CsCl-YCl3-9.5%HCl-H2O quaternary system at T=298.15 K was investigated by the physico-chemical analysis method and the corresponding phase diagram was plotted. The crystallization of two new double salts Cs4YCl7.10H(2)O (4 : 1 type) and Cs3Y2Cl9.14H(2)O (3 : 2 type) was successful and they were obtained from the complicated system directly. Both were identified and characterized by X-ray, thermal analysis method of TG-DTG, DSC. The fluorescence experiments show that up-conversion phenomenon does not exist in compounds CS4YCl7.10H(2)O and Cs3Y2Cl9.14H(2)O.
