Polyethylenimine (PEI, M w 50,000) was employed as a dispersant to stabilize nanosized ZrO 2 (3 mol% Y 2 O 3 doped) aqueous suspensions. Adsorption isotherm measurements demonstrated that the plateau region of coverage was reached when polymer concentration approached 1.0 wt% dry weight basis of ZrO
