THERMODYNAMICS, CLUSTER FORMATION AND CRYSTAL-GROWTH IN HIGHLY SUPERSATURATED SOLUTIONS OF KDP, ADP AND TGS

The activity of supersaturated solutions of KDP, ADP and TGS was measu red over a large portion of the metastable region by employing electro dynamic levitation of single solution droplets. These data were used t o calculate the location of the spinodal curve in each system, as well as the critical cluster size and degree of association. In addition, crystal growth and nucleation kinetics data found in the literature ha ve been reexamined using chemical potential in place of concentration in calculation of the supersaturation.
