Abstract
The Ba1−x Sr x TiO3 materials have received increased attention as one of the most important materials for electroceramic components, such as high dielectric ceramic capacitors, tunable phase shifters and PTCR. In this paper the effect of 0.5; 1; 1.5; and 2 mole% of Bi2O3 addition on microstructure, structure, dielectric properties (i.e., dielectric constant ϵ′, and dielectric loss factor tan δ), as well as pyroelectric and thermally stimulated depolarization currents (TSDC) of (Ba0.8Sr0.2)TiO3 ceramics have been investigated. The distinct correlation between Bi2O3 content, wide maxima in TSDC, anomalies in ϵ′ (T) and tan δ (T) characteristics occurring within the range of the paraelectric phase was confirmed. Changes of electric conductivity and Seebeck's coefficient, caused by Bi2O3-additives, were also studied.
