Solubility in the NaNO3-NH4NO3-KNO3-H2O system

Solubility in the NaNO 3 -NH 4 NO 3 -KNO 3 -H 2 O four-component water-salt system was studied for the first time at 25, 40 and 60°C. The crystallization boundaries were determined for individual constituent salts, the double salt 3KNO 3 · NH 4 NO 3 , potassium nitrate-based solid solutions, and amm...

Zusammenfassung:	Solubility in the NaNO 3 -NH 4 NO 3 -KNO 3 -H 2 O four-component water-salt system was studied for the first time at 25, 40 and 60°C. The crystallization boundaries were determined for individual constituent salts, the double salt 3KNO 3 · NH 4 NO 3 , 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.
