Zhang-Steenwinkel, H. Castricum, A. Bliek, E. Esveld] Dielectric properties of La1−x Ce x MnO3 perovskites are investigated in order to assess the heating behaviour in the wider context of the use of perovskite coatings in microwave assisted soot filter regeneration. Dielectric permittivities in the radio and microwave region for these perovskites were determined at room temperature. The dielectric constant and dielectric loss are related to ionic conduction at low frequencies, while at microwave frequencies storage and loss mainly proceed through reorientation of molecular dipoles. The dielectric constant rises for a higher degree of La substitution by Ce, which is explained by an increase of the number of cation/oxygen vacancies. Concurrently the mean perovskite crystallite size decreases, which is possibly related to defect formation. The dielectric constant declines for x≥0.3, along with the formation of a separate, low dielectric permittivity CeO2 phase. The La-Ce-Mn perovskites are further shown to exhibit a high thermal stability during repeated heating/cooling cycles. Springer Science+Business Media, LLC, 2007 Zhang-Steenwinkel Y.
