Phase diagrams for quaternary salt solutions

Phase diagrams for two quaternary salt solutions are shown in the tabs below. This type of phase diagrams are for example useful when designing fractional crystallization processes.

  • The sodium chloride, potassium chloride, calcium chloride – water system. This is a system with three cations and one anion which can be plotted in a triangular Jänecke diagram.
  • The sodium chloride, potassium chloride, sodium sulfate, potassium sulfate – water system has two cations and two anions and is therefore plotted in a quadratic Jänecke  diagram
