The effect of Al2O3 nanoparticles on the crystalline phase, morphology and adjustment of dielectric properties of ZnTiO3 nano-powder has been investigated. The structural and morphological properties were investigated by X-ray diffraction (XRD), field emission-scanning electron microscope (FE-SEM) and Fourier Transform infra-red (FTIR) spectroscopy. The average particle size of the rhombohedral perovskite structure ZnTiO3 and Al2O3/ZnTiO3 is about 61 nm and 53 nm, respectively. Introduction of Al2O3 NPs induces structural and morphological modifications, causes an adjustment in pore structure and textural characteristics of ZnTiO3 nano-powder. In addition, the dielectric results have appeared that the dielectric constant and dielectric loss, [tan(δ)] are decreased with introducing the Al2O3 NPs in the crystalline nano-sized ZnTiO3 powders. The gained results are presented in detail.
