Abstract: The solubilities of the ternary system, Y(NO3)3·3H2O·Bl5C5·C2H5OH, at 18℃ have been investigated by the modified semimicro phase equilibrium method. The results indicated that there are two solubility curves for this ternary system, the long one correspounds to the solid phase of the complex, Y(NO3)3·B15C5·3H2O· 1.5C2H5OH, the short one to solid phase of B15C5. The curve of refractive indices for saturated solutions consists of two branch lines, which correspound with two branch lines of solubility curve. We have not found another complex species having different ratios, Y/crown.
