Polarization Mechanisms in Thermal Stable Microwave BLT Ceramics Part 2: Paramagnetism suppress soft mode
Main Article Content
Abstract
The objects of study are vacant perovskite-like structures of BaLn2Ti4O12 (BLTs). These polycrystalline dielectrics allocated among many other microwave dielectrics that their permittivity ε is several times higher than in other types of microwave ceramics. Electronic relaxation process with extremely low activation energy has no influence on microwave losses but defines BLTs dielectric thermal stability. Very low relaxation time is due to the nanoscale clusters, electronic by their nature and build-in the BLT structure. Dielectric losses of this type ceramics are associated with structural disordering, especially if the second polar phase is present. References 3, figures 4, tables 2.
