Abstract

Nielsen's equation has been applied for cooling crystallization of KCl from watery solutions. In the calculations activities are used instead of concentrations, the temperature and concentration dependence of both the activity and diffusion coefficients are considered. It is found that A) the interfacial tension between the crystal and its saturated solution is < 2.5 erg/cm2, which is less by two orders of magnitude than that of between crystal and vacuum; B) homogeneous nucleation can take place even at very small supersaturations (ln S < < 0.01), which is unusual in precipitation.
