Dispersed ZrO2 nano-laminae were synthesized at low temperature using zirconium oxynitrate and polyvinyl pyrrolidone (PVP) as reaction materials. High-resolution transmission electron microscopy (HRTEM) of individual ZrO2 nano-laminae showed that each piece of ZrO2 nano-laminae was assembled by large numbers of ZrO2 nanocrystals. The bulk dispersed ZrO2 nano-laminae could be observed in situ from scanning electron microscopy (SEM) images. The results of X-ray diffraction (XRD) showed that the crystallographic phase of ZrO2 nano-laminae was cubic ZrO2. Experiments indicated that the morphologies and phase composition of ZrO2 nano-laminae were affected by the calcined temperature. PVP plays an important role in the formation process of dispersed ZrO2 nano-laminae.
