Abstract

A group of (1−x)Bi(Zn1/2Ti1/2)O3-χABO3 (ABO3=BaTiO3, NaNbO3, BiScO3 and Bi1/2K1/2TiO3) polycrystalline ceramics were prepared by solid-state processing techniques. Based on x-ray diffraction results, the presence of Bi(Zn1/2Ti1/2)O3 in the solid solution decreases the structure stability of perovskite phase. The dielectric characterization revealed that the trends of transition temperature Tm as a function of composition of Bi(Zn1/2Ti1/2)O3-ABO3 could be described into two groups. The first one is Tm decreased until second phase appeared and the second one is Tm decreased and then increased as Bi(Zn1/2Ti1/2)O3 content increased. In addition, with substitution of Li for Na of NaNbO3-Bi(Zn1/2Ti1/2)O3 the diffuseness of the transition peak decreased and transition temperature increased.
