The solubility and refractive indices of saturated solution of the ternary system at 30℃ have been studied and the corresponding equilibrium diagrams are constuct- ed. The system of Zn(NO3)2 is a simple one. The eutectic compositions are Zn(NO3)2 50. 86% and CH3CONHCONH2 11.70%.The phase equilibrium data can be used in formulat- ing controlled release fertilizers.
