    Abstract:

    Nanometer-sized zirconia (ZrO2) powder was synthesized from ZrOCl2·8H2O through a hydrothermal method. The aqueous suspension stability of ZrO2 powder was studied by zeta potential measurement and particle size analysis. Results show that ZrO2 nanoparticles are ellipsoidal with uniform particle size, and the particle size is mainly in the range of 40–100 nm. The isoelectric point (IEP) occurs at pH=9.0. ZrO2 particles are well dispersed far from IEP and severely agglomerated near IEP.
