Sie wirkt im Schönen wie im Hässlichen: Die Kristallisation bestimmt die Form von Edelsteinen, bringt aber auch den Kalk in die Waschmaschine. Wie sie abläuft, schien längst geklärt. Doch Wissenschaftler des Max-Planck-Instituts für Kolloid- und Grenzflächenforschung kratzen jetzt an der etablierten Theorie, die viele Phänomene kaum erklären kann. Die Forscher untersuchten die Kristallisation von Kalziumkarbonat, landläufig als Kalk bekannt. Dabei haben sie herausgefunden, dass sich anders als bislang angenommen auch in Wasser mit wenig gelöstem Kalziumkarbonat stabile Nanocluster bilden. Aus diesen winzigen Kalkteilchen entstehen schließlich die Ablagerungen, die irgendwann die Waschmaschine lahm legen.
