摘要
The equilibrium solubility of one CsCl-YCl3-H2O ternary section of CsCl-YCl3-9.5%HCl-H2O quaternary sys-tem at T=298.15 K was investigated by the physico-chemical analysis method and the corresponding phase dia-gram was plotted. The crystallization of two new double salts Cs4YCl710H2O (4∶1 type) and Cs3Y2Cl914H2O (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 Cs4YCl7·0H2O and Cs3Y2Cl9·4H2O.
