Abstract: Zinc titanate (ZnTiO3; ZT) powders were successfully prepared by a combustion technique. ZT powders were heated at various calcination temperatures, ranging from 500 to 850 ºC, for 2 h at a heating/cooling rate of 5 ºC/min. Powder samples were characterized using thermogravimetric (TGA), differential thermal analysis (DTA), X-ray diffractro meter (XRD), scanning electron microscopy (SEM) and laser particle size analyzer (LPSA). The second phases such as ZnO and TiO2 were detected in the powders calcined below 800 ºC. A single perovskite of the ZT powders was found with calcination temperatures at 800 ºC. The TGA-DTA results corresponded to the XRD investigation. The shape of crystalline will be changed as increasing the time of calcination temperature. According to SEM and LPSA analysis ultra-fine powders of ZT were obtained.
