Abstract
The action of water vapor on nominally pure BaCeO3 perovskite at 850 K causes hydrogen to be incorporated into the lattice and a thermally m etastable state to form. The lattice symmetry changes as a result of a n orthorhombic-pseudocubic transition which takes place at a temperatu re substantially lower than the known thermally initiated rhombohedral -cubic transition at 1173 K.
