Abstract
CuSO4-CO(NH2)(2)-H2O and ZnSO4-CO(NH2)(2)-H2O ternary systems have been inv estigated by isothermal method at 30 degrees C. Their solubility diagrams a nd refractive index-composition diagrams have been constructed. New ternary compounds formed in each system respectively, CuSO4 . 3CO(NH2)(2) . H2O in congruently dissolved in the former system and ZnSO4 . CO(NH2)(2) . 2H3O co ngruently dissolved in the latter and new compounds were confirmed, by IR, TG and X-ray diffraction methods.
