Influence of Polyelectrolyte Dispersants on Properties of Y-TZP Suspensions

Wang Ju

Abstract

Polyelectrolyte dispersants NH4PAA and NH4PMAA were synthesized by controlling proper reaction parameters.Isotherm adsorption and IR spectra of Y-TZP suspensions indicated that optimum content of dispersant was 2 wt% at pH 10. Surface structure was obviously affected by the absorbed polymer.The zeta potential and rheology of Y-TZP suspensions were investigated. Low viscosity Y-TZP suspensions with a solids loading of 47 vol% was obtained by adding NH4PAA as dispersant.
