摘要
Experimental results of solubility and growth kinetics measurements of sodium chloride crystals in multicomponent systems at 303 K are given. The effect of several solutes in elevated concentrations on the growth and dissolution kinetics is analysed on volume diffusion and surface integration steps: While the diffusion of ions within the solution decreases by the presence of foreign ions, the integration resistance can increase (mobile or immobile adsorption of foreign ions) or may even be reduced in some cases (due to a decreased surface energy).
