Abstract
Nanocrystalline zinc oxide powders were successfully prepared by Pechini method. The polymeric precursors were prepared using zinc acetate and a mixed solution of citric acid and ethylene glycol as a chelating agent and reaction medium respectively. The polymeric precursors were calcined at temperatures from 500 to 900°C for 1 h. The resulting powders were characterized by x-ray powder diffraction, thermogravimetry, and Fourier-transform infrared spectroscopy. Well-crystallized zinc oxide was obtained at low-temperature about 500°C. The average crystallite size was estimated as 47–73 nm in the range of 500–900°C and the lattice parameters were compatible with the values found in literature.
