Аннотация: 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 thПоказать полностьюe magnitude of root mean square polarization. The results obtained are discussed together with the data on the structure and dielectric properties.
