Abstract
Differential scanning calorimetry was used to study phase transitions (PT) in the perovskite BaCeO3. It is shown that its phase state is determined by a second-order lambda transition at T-tr = 520-540 K and a first-order del ta transition at T-tr = 600-670 K. Differences in PT parameters between cer amic and fused BaCeO3 have been established. (C) 1998 American Institute of Physics. [S1063-7834(98)03211-0].
