The kinetics of gelation and flow properties of fumed silica suspensions were investigated in pure water and a water/glycerol mixture, as a function of temperature and pressure. In pure water, the gelation time was determined by following the evolution of the storage and loss moduli versus time at several frequencies and temperatures between 18 and 35°C. Increasing the temperature increased the aggregation...
Multiphase light scattering and transient-dynamic rheometry were used in combination in order to control the stability, rheology and gelation of aqueous Aerosil 200 suspensions with regard to the influence of pH, particle and electrolyte concentrations. Effects of these parameters were studied by obtaining the critical concentration of particles for transition from Newtonian to shear thinning flow...
