Abstract

The equilibrium solubility of the quaternary system TbCl3-CdCl2-HCl(7.92 mas. %)-H2O was determined at 298K and the corresponding equilibrium diagram was constructed. The quaternary system is complicated by the three equilibrium solid phases: CdCl2 · H2O, TbCd4Cl11 · 14H2O (4: 1 type), and TbCl3 · 6H2O, of which the new compound Cd4TbCl11 · 14H2O was found to be congruently soluble in the system. The new compound obtained was identified and characterized by the method of X-ray diffraction and the thermal analysis methods of thermogravimetry-differential thermogravimetry (TG-DTG).
