AbstractZirconium oxychloride, urea and ammonia have been used to produce the precursor by the precipition method. The precursor was heat-treated to obtain the zirconia powders. Differential thermal analysis shows that the precursor changes into amorphous zirconia at 300 degrees C, and then transforms to tetragonel zirconia at 450 degrees C. The processes are endoergic and exoergic, respectively. XRD analysis shows that the monoclinic zirconia not can be obtained below 700 degrees C. The content of monoclinic zirconia increases as the calcination time increases. The zirconia powders so obtained are nanostructured. The size of the powders increases quadratically with the calcination temperature. The particle size increases linearly with calcination time.
