Sažetak
The dimensions and properties of nanoparticles enable their wide application. Today, various syntheses are being developed to obtain nanoparticles and one of the effective methods is sonochemical synthesis resulting from ultrasonic cavitation [1, 2]. The aim of this work is to determine the influence of the duration of synthesis, amplitude and pulse duration of ultrasound assisted synthesis on the final phase ratio and crystallite size of ZrO2 nanoparticles. For the synthesis, ZrO(NO3)2 · xH2O and ethylenediamine were used in aqueous media. IR analysis showed that the qualitative composition of the precursor is the same and does not depend on the synthesis parameters. The synthesis and pulse duration have the greatest effect on the composition after calcination. The experiment showed that the time of precursor synthesis has a significant effect on the proportions of phases in the product. Quantitative PXRD analysis revealed a presence of monoclinic and tetragonal ZrO2 phases in the samples after calcination. An increased proportion of the monoclinic phase was detected in samples sonicated for up to 15 min and samples sonicated with ultrasound pulse for 1 and 2 s. The pure tetragonal phase is present only in a sample sonicated for 30 min.
