Abstract

The phase diagram for the ternary system K₂Cr₂O₇ + KNO₃ + H₂O was determined at four temperatures, (10, 20, 30, and 40) °C. In addition, the densities of the saturated aqueous solutions were measured. The experimental results show that, in the temperature range (10 to 40) °C, only potassium nitrate and potassium dichromate were present as solid phases and that the solubility of KNO₃ was almost independent of the K₂Cr₂O₇ concentration, whereas the solubility of K₂Cr₂O decreased sharply with increases in the concentration of KNO₃.
