Along with titanium oxides and alumina hydroxides calcium carbonates and china clays are the most important coating pigments in paper and coating industry. They are the main ingredients in coating colours and due to commercial reasons the solid content of such dispersions has to be as high as possible. In high solid dispersions particle particle interaction and interaction between particles and other ingredients differ considerable from the behaviour in dilute state and hence the storage stability of the dispersion could be strongly influenced. Storage stability and sedimentation velocity, respectively, of china clay dispersions were investigated by centrifugal separation analysis related to the rheological behaviour in dependence on solid concentration.
