The rheological phase reaction method was used to obtain the zirconia spherical particles with monodispersity and single-scale. And based on this, we got the colloidal dispersion of Zirconia (ZrO2). Mesoporous zirconia were successfully synthesized by vacuum filtration or gravitational deposition as assembly methods using monodispersed PMMA as template. The precursor was studied by FT-IR, TG and DTA, these results further revealed that the precursor is ZrO(C6H5COO)2·2H2O. By the phase analysis in the XRD patterns it was proved that the ZrO2 crystallites have monoclinic phase structure. SEM results indicated that the aperture size is from 50-500 nm and increases with the process conditions changing, moreover, the sample has good thermal stability. This study shows the controllability of ZrO2 macroporous materials’ aperture size was realized at some extent.
