Abstract :
Spherical ZnO microspheres were obtained in a simple system using a short time process, without catalysts, at atmospheric pressure and using water as oxidant agent. Analysis with SEM shows the microstructures have spherical shapes covered with pencil-like structures. XRD spectrum reveals that as-synthesized ZnO products crystallize in the wurtzite phase.
