ABSTRACT A conventional solid-phase sintering process was used to fabricate the (1 − x)Na0.5Bi0.5TiO3-xBaTiO3 ceramics (x = 0, 0.04, 0.06, 0.08 and 0.1). X-ray measurements showed that all samples have a perovskite structure. The bulk density of the obtained samples exceeds 95% of the theoretical density. The thermal (DSC, dilatometry) and dielectric properties of these ceramics were investigated in a wide temperature range. Anomalies of the thermal expansion strain were observed at the temperatures which are not related to any phase transitions. The transition temperatures observed by means of thermal measurements are in good agreement with those obtained from dielectric studies.
