%X The influences of several anionic dispersants on the colloidal and rheological properties of nanosized Y-TZP suspensions were investigated. Isothermal adsorption was conducted to study the interaction between the dispersant and the powder. It was found that these dispersants adsorbed chemically on the powder. The zeta potential of Y-TZP powder at alkaline region changed from -20mV to -40-50mV after the addition of dispersants. Rheological measurements showed that the dispersant addition significantly enhanced the fluidity of the slurry. The deflocculation mechanism of the dispersant for the suspension was finally discussed.
