Abstract

Abstract: It is demonstrated that the dielectric properties of ceramics in the 0.6PMN–0.4PZN system have been studied as a function of different synthesis method at various temperatures. A detail and systematic study of phase, grain size and dielectric properties has been carried out by using X-ray diffraction, SEM techniques and dielectric measurement. Our analysis revealed that the optimum results were obtained for ceramics synthesized by columbite method as compared to combustion. The maximum dielectric constant was found to be 25, 300 with Tc 46 °C at 100 Hz by columbite method whereas 17, 449 with Tc 43 °C at 100 Hz by combustion method. The article concludes with the brief discussion of promising method with acceptable relaxor behavior.
