dc.description.abstractPolycrystalline ceramics based on strontium titanate (SrTiO3) have attracted great attention in recent years due to their interesting dielectric properties, e.g. high electric permittivity and low dielectric loss. SrTiO3 has many applications in electronic devices, sensors, actuators, fuel cells, among others. Recently, the effects of dopants on the dielectric properties of SrTiO3 have been investigated. Lui et al. [1] were the first to report a giant electric permittivity in Sr0.09Pr0.01TiO3 (> 3,000) at room temperature. In this work, the effect of Pr (0.025, 0.05 and 0.075% mol Pr) on the microstructure and dielectric properties of SrTiO3 was studied in detail. Samples were characterized by density measurement, X-ray diffraction, scanning electron microscopy and impedance spectroscopy. The results show that sintered samples at 1500 ºC/6 h exhibit high densities (> 96% of the theoretical value), independent on the additive content. The average grain size of SrTiO3 increases slightly with Pr addition. Specimens containing 0.075% mol Pr show high giant permittivity (about 30,000) at 540 ºC.pt_BR
