Abstract :
(Na_0.5 , Bi_0.5)(Ti_0,8 Zr_0,2)_1-x(Sb_2/3 , Ni_1/3)_xO_3 (NBTZSN) ceramics with x= 0.05 and 0.1 were synthesized using a high-temperature solid-state reaction technique. X-ray diffraction (XRD) technique, FTIR and scanning electron microscopy (SEM) were used to study the structural and microstructural properties of the compounds, respectively. The XRD study confirmed the formation of a single-phase polycrystalline compound with tetragonal crystal structure and minority of pyrochlore phase at room temperature. Microstructural analysis of the surface of the compounds exhibits that there is a change in grain size, shape and density on introduction of (Sb) and (Ni) in (NBTZ).
