Megjegyzések:	The formation mechanism of ZnO nanopowders was investigated by appropriate experimental methods. The studied samples have been obtained using a wet chemical route based on Zn(NO3)2?nH2O (ZAH) - (CH2)6N4 (HMTA) system in which the molar ratio of the components was 4:1 and 2:1. From the same solution, depending on the experimental conditions used, gels, precipitates or hydrothermally grown powders were obtained. Thermal decomposition of the as-prepared powders was analysed by simultaneous thermogravimetric and differentialthermal analysis (TG/DTA) and differential scanning calorimetry (DSC) methods. X-ray diffraction method (XRD), FT-IR Spectroscopy and Scanning Electron Microscopy (SEM) were used to study the structure and morphology of the obtained samples and their evolution with thermal treatment. The correlation between the preparation parameters and the properties of the resulted ZnO powders was established.
