Synthesis of perovskite type of zinc titanate nano-crystal powders via combustion technique

Abstract EN

Zinc titanate (ZnTiO3 ; ZT) powders were successfully prepared by a combustion technique.

The ZT powders were heated at temperature from 500 ºC to 850 ºC for various times 2, 4 and 6 h.

Powder samples were characterized using thermogravimetric (TGA), differential thermal analysis (DTA), X-ray diffractrometer (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 shape of crystalline will be changed as increasing the time of calcination temperature.

The TGA-DTA results corresponded to the XRD investigation.

According to SEM and LPSA analysis nano-crystal powders of ZT were obtained.
