Synthesis of pure nanocrystalline ZrO2 via a simple sonochemical-assisted route

Pure nanocrystalline zirconia was synthesized via a sonochemical-assisted method based on the reaction between zirconyl nitrate and propylenediamine. Here, propylenediamine for the first time was used as precipitating agent to fabricate nanocrystalline zirconia via a sonochemical-assisted method. The effect of solvent and concentration of propylenediamine on the morphology and crystallite size was investigated. It was shown that morphology and crystallite size of the as-synthesized products could be greatly affected by these parameters. The as-prepared products were characterized by SEM and TEM images, XRD patterns, FT-IR and EDS spectroscopy.
