Preparation of Stabilized Al_2O_3 Aqueous Suspension

In this paper, polyelectrolytes, PMAA NH4, was used as dispersant, the rheological properties of suspensions and the effect of dispersant concentration on suspension stability were studied by means of the collidal elecosteric stabilization mechanism. Sedimentary volume was used to judge the stability of suspension. The stabilized and dispersed suspension with high solids loading (58vol %) was prepared at the best ph value and dispersant concentration.
