The paper presents a method for obtaining nanoparticles of ZnO by thermal decomposition of the Zn-containing compounds. The experiment was based on the thermal decomposition of basic zinc carbonate to zinc oxide (with a content of 58-61 wt.%). Basic zinc carbonate was analysed by derivatography and then annealed at a selected temperature (about 600ºC) for about 1 h. Products of thermal decomposition of the compound were studied by XRD analysis and SEM scanning microscopy.

Zno Powder

The ZnO powder was successfully obtained by calcining the basic zinc carbonate, which was synthesized from clinker digestion solution of zinc oxide ore using analytical Na2CO3. The factors of mol ratio of Na2CO3to ZnSO4and reaction temperature were discussed at stirring intensity 400 rpm. Both the obtained basic zinc carbonate and ZnO powders were characterized using XRD, EDS and SEM. The thermal decomposition of basic zinc carbonate was also investigated below 600°C. The results show that the ZnO powder was wurzite hexagonal structure and the well-crystallized ZnO powder was uniformly spherical particles and distributed in a narrow range.
