English Abstract
The thermal expansion properties of the ceramic compositions Ba1−yLayTi1−y/4O3 (y = 0.0, 0.026, 0.036, 0.054) and Ba1−yBi2y/3Ti1−xZrxO3 (y = 0.10; x = 0.0, 0.04, 0.05, 0.10, 0.15) were determined in the temperature range ...Read more >
The thermal expansion properties of the ceramic compositions Ba1−yLayTi1−y/4O3 (y = 0.0, 0.026, 0.036, 0.054) and Ba1−yBi2y/3Ti1−xZrxO3 (y = 0.10; x = 0.0, 0.04, 0.05, 0.10, 0.15) were determined in the temperature range 120–700 K. We report the temperature-dependent measurements of the strain, thermal expansion coefficient and the magnitude of root mean square polarization. The results obtained are discussed together with the data on the structure and dielectric properties.Read less <
