Abstract: A new method to prepare ZrO2 nanoparticles is described.Precursors of ZrO2 were synthesized by solid state reaction of ZrOCl2·8H2O to C2H2O4·2H2O.Precursors were characterized by TG/DSC and the properties of zirconia were studied with aids of XRD,TEM.The effect of grinding and calcination on crystal was also investigated.The result shows that ultrafine zirconia with average particle size of 11nm has high purity and even distribution,and the main phase of the powder is tetragonal phase.

Key words: nanometer； zirconia； solid-state synthesis；
