The freezing of suspensions of particles is not always a uniform phenomenon; in certain conditions it leads to a modification of the redistribution of particles and the growth of crystals. These results have been obtained by researchers at the Laboratoire de Synthèse et Fonctionnalisation des Céramiques (CNRS/Saint Gobain) and the Laboratoire Matériaux, Ingénierie et Sciences (CNRS/INSA Lyon) by observing,through X-ray imaging at the European Synchrotron Radiation Facility (ESRF), the movement of particles while they are being frozen.Source:CNRS(France)
