Fraunhofer Institute for Ceramic Technologies and Systems IKTSThe processing characteristics of high concentrated suspensions are highly determined by their viscosity, homogenity and their state of dispersion. These parameters can be influenced by adding fitting dispersants and in this way the characteristics of the suspension can be adjusted. To make the right decision about which dispersant to use, knowledge about the interactions between particles, dispersant and consumables are necessary. Besides the characterization of electric charge proportion on the particle surface through electroacoustic methods, rheological measurements in oscillation and rotation are made. Through combination of measurement technology, a simultane capture of electro static and steric effects in for further processing relevant concentrations is possible.
