摘要：
Solubility in the NaNO3-NH4NO3-KNO3-H2O four-component water-salt system was studied for the first time at 25, 40 and 60A degrees C. The crystallization boundaries were determined for individual constituent salts, the double salt 3KNO(3) center dot NH4NO3, potassium nitrate-based solid solutions, and ammonium nitrate-based solid solutions. The reported experimental data have been used to optimize a circular isohydric process for preparing potassium nitrate involving additional salts.
