Measurements show that TiO2 aggregates have a fractal structure. Therefore, their dispersibility can be studied based on their morphol. This is best carried out in laminar Couette flow, as its flow profile has been well-established. This permits the investigation of the effect of process parameters on the break-up of the aggregate, and, via (micro)rheol. models, the switch to complex industrial size redn. app. [on SciFinder (R)
