Предметные рубрики: HEAT-CAPACITY CERAMICS BA(TI1-XZRX)O-3 FERROELECTRICS BEHAVIOR BATIO3 BATI0.65ZR0.35O3 CONDUCTIVITY PEROVSKITES CHEMISTRY Ключевые слова (''Своб.индексиров.''): barium--dielectric properties--lanthanum--phase diagrams--polarization--thermal stress--zirconium--ceramic compositions--root mean squares--temperature ranges--temperature-dependent measurements--thermal expansion co-efficient--thermal-expansion properties--thermal expansion 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 the magnitude of root mean square polarization. The results obtained are discussed together with the data on the structure and dielectric properties.
