Colloidal suspension are widely used in a number of industrial applications and are usually formulated to display well-defined flow behaviour. Above a certain particle concentration suspensions are generally non-Newtonian fluids, whose flow properties are influenced by a large number of factors. The increase in particle concentrations often causes a very complex rheological behaviour of suspension. Rheological properties and especially their concentration dependence can provide detailed information about the microstructure of the suspension. Results of investigations on the effect of particle properties and various types of thickeners on rheological parameters of suspensions to be applied in the pharmaceutical industry, are presented in this study.
