Abstract

Solubility data in the diagonal sections of the quaternary reciprocal 2KCl + Ca(NO3)2 → 2KNO3 + CaCl2–H2O system at 25 and 15°C are presented. It has been shown that the quaternary system has no stable diagonal at the studied temperatures, but contains a stable pair of salts, namely, potassium nitrate and calcium chloride. The obtained data can be used to optimize the thermal and concentrational parameters of the synthesis of potassium nitrate from calcium nitrate and potassium chloride.
