| Abstract: The isothermal solubilities of the ternary systems Cu(NO3)2-CO(NH2)2-H2O (30℃) and La(NO3)3-CO(NH2)2-H2O (25℃) have been studies. There are 4 new compounds Cu(NO3)2·4CO(NH2)2、 La(NO3)3·2CO(NH2)2·3H2O、 La(NO3)3·4CO(NH2)2·H2O and La(NO3)3·6CO(NH2)2 found in the systems, which are congruently to dissolve in water at room temperature. These compounds have been characterized by IR, X-ray and TGA. |
