Structural and electrical properties of ferroelectric Na0.5 (Bi1-xPrx )0.5TiO3 (x=0.00 and 0.10) ceramics synthesized by Sol-Gel method

Ferroelectric Na0.5(Bi1-xPrx)0.5TiO3 (x=0.00, 0.10) ceramics have been synthesized through sol-gel method. The phase formation has been confirmed by X-ray diffraction analysis of ceramics annealed at 800°C. The relaxation mechanism is observed from variation of dielectric constant with respect to temperature and frequency. Substitution of Pr reduces vacancies and defects identified from leakage current measurements. Further, the polarization Vs electricfield (P-E) measurements have been performed at room temperature.
