✦ Synopsis

This study reports experimental results about the shrinkage of particle networks produced by pH-induced destabilization of dense colloidal suspensions. The resulting solid networks exhibit no syneresis effects, at least prior to aging of the gel. From this lack of syneresis it is concluded that the solidification in wet particle systems either is not purely determined by energy (but is also influenced by entropic effects) or cannot be explained within the framework of (static) equilibrium thermodynamics at all.

Using diffusing-wave spectroscopy, we followed the aggregation and gelation of concentrated (30 vol%) alumina suspensions. The suspensions were destabilized by either shifting the pH to the isoelectric point or by increasing the ionic strength. Both effects can be achieved continuously and homogeneo

The aim of this study is to analyze the behaviour of dense colloidal suspensions in flow by acoustic spectroscopy. The destabilization and the aggregation of stable colloidal silica dispersions in a stirred tank are obtained by the addition of salt. Experiments were made in order to observe the infl
