| Abstract: | Phase formation and dielectric properties of 0.75PNN 0.25PT relaxor ferrelectric Ceramic was investigated.The results showed that the addition of excess Ni(Ac) 2 was found to restrain the generation of pyrochlore phase and resulted in pure perovskite phase.A relaxor ceramic with good dielectric properties was obtained. |

| Keywords: | lead nickel niobate relaxor ferroelectic perovskite structure |
