Electrosteric Stabilization of Al2O3, ZrO2, and 3Y–ZrO2 Suspensions: Effect of Dissociation and Type of Polyelectrolyte

“…The effects were studied as function of time (36). In a previous study it was found that the pH of aqueous 3Y-ZrO 2 suspensions without polymer present decreased and the zeta potential increased in the acidic pH range as function of time, due to the dissolution or exchange of potential determining ions, and due to dissolved but redeposited hydrolyzed ion species formed (37). In the presence of 0.11 wt% polyacrylate the zeta potential curve exhibits a wavy decrease in the positive value at pH ca.…”
