The development of high-Tm relaxor materials for high-temperature high-power density electrotransduction applications and high-temperature capacitors in automobile applications was studied. The relaxor behavior was confirmed by studying polarization reversal and frequency and temperature dependent dielectric constant behavior. It was found that the relaxor behavior arose due to the creation of the chemical heterogeneity by localized cationic ordering which depends on the substitution rate.
