Sažetak
Dimensions and properties of ZrO2 nanoparticles enable their wide application. For the application of nanoparticles, energy-efficient preparation of small and pure particles without impurities is necessary ; therefore, sonochemical synthesis is increasingly the chosen method. Here we report the sonochemical synthesis of ZrO2 nanoparticles and the influence of the synthesis duration, the amplitude and the duration of the ultrasound- assisted synthesis pulse on the final phase ratio and crystallite size of ZrO2 nanoparticles. For this simple and most of all cost-effective synthesis of ZrO2, a nanoparticles stabilizer is necessary, to prevent their growth. Ethylenediamine was used for this purpose. The qualitative composition of precursors and calcined samples was determined by Fourier transform binfrared spectroscopy (FTIR). Synthesized compound was further structurally characterized by powder X-ray diffraction (PXRD), while the nanoparticle size, grain size, size distribution, and morphology were investigated by transmission electron microscopy (TEM).
