ZnO is one of the versatile metal oxides with a wide range of applications in energy, catalysis, medicine and lightweight technology. Especially the nanoscopic size leads to enhanced me-chanical, physical and chemical properties. In order to produce a wide range of different di-mensional ZnO nanoparticles with narrow size distribution, within the scope of the work, the inexpensive hydrothermal synthesis route was selected. It has been shown that the morphol-ogy can be easily controlled by the choice of appropriate synthesis parameters like tempera-ture, time, pH value of solution and additives. Influence of the parameters on the nanoparti-cles morphology was characterized by electron microscopy and raman spectroscopy. To determine whether the dimensional stability at high temperatures is ensured, nanopowder heat treatments at temperatures over 500 °C were carried out. The confirmed high thermal dimen-sional stability allows further investigations of the nanopowder as high-temperature semicon-ductors or as reinforcing nanoparticles in composites manufacturing processes.
