Abstract
Based on the Hard-Sphere Approximation applied to colloidal particles in strong repulsive interaction, a model is proposed for the zero shea r viscosity of concentrated (colloidal) suspensions, which takes accou nt of phase transitions in HS systems. A good agreement is observed be tween this model and viscosity data on silica and Inter suspensions.
