✦ Synopsis

Metastable zone width measurements in aqueous solutions of 18 well soluble substances have been .sed for the characterization of the nucleation process in absence and in presence of crystals. As could be expected, it has been confirmed that the specific surface energy of the critical nucleus is only slightly decreased by the presence of crystals. The effect is almost negligible for the critical nucleus size. Both of these quantities can be correlated with the solubility of the substance.

Messungen der Breite des metastabilen Gebietes in waDrigen Losungen von 18 gut loslichen anorganischen Substanzen wurden zur Charakterisierung des Keimbildungsprozesses in An-und Abwesenheit von Kristallen benutzt. Der Erwartung nach wird die spezifische Oberflachenenergie des kritischen Keimes durch die Anwesenheit der Kristalle nur unwesentlich niedriger und seine GroDe wird von der Anwesenheit der Kristalle kaum beeinflu&. Diese beiden GroDen konnen mit der Loslichkeit korreliert werden.
