英文摘要	The temperature-dependent structure and dielectric properties of Bi0:95Ba0:05Fe0:95 Ti0:05O3 ceramic are studied systematically. At the temperature range of 25-800 degrees C, the cell parameters are increasing, this indicates its distorted rhombohedral R3c structure. A structural phase transformation from rhombohedral R3c to cubic Pm3m is observed at 850 degrees C. The thermal expansion coefficients in the temperature range 25-700 degrees C are calculated. Meanwhile, the temperature-dependent dielectric constant (epsilon') and dielectric loss (tan delta) at different frequencies are measured. This work attempts to show the thermodynamic stability and the effect of charge defects on the electric properties for doped BiFeO3 ceramics.
