Pressure-Induced Phase Transition and Structural Evolution of Single-Crystal CaSnO3 Perovskite
Calcium stannate (CaSnO3) is a widely used analogue of bridgmanite (MgSiO3), capable of undergoing a pressure-induced perovskite-to-postperovskite phase transition under accessible experimental conditions. In this study, high-quality single-crystal CaSnO3 perovskite was synthesized by solid-state reaction. Its struct...
