摘要：
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 λ transition at Ttr=520–540 K and a first-order δ transition at Ttr=600–670 K. Differences in PT parameters between ceramic and fused BaCeO3 have been established.
