Influence of Temperature on Stability of Aqueous Alumina slurry containing Polyelectrolyte Dispersant

摘要

Effects of temperature on the stability of aqueous alumina slurry dispersed with polyelectrolyte have been studied. An adsorption experiment was per- formed to investigate the mechanism of the temper- ature-dependent stability in the system. Viscosity measurement and sedimentation results show that temperature dramatically affects the stability of slurry. The adsorption of dispersant increases with increasing temperature and the stability is strongly dependent on the adsorption state.
