Calcium stannate (CaSnO3) is a perovskite-structured ceramic compound that functions as a wide-bandgap semiconductor, representing an emerging class of metal oxide materials for optoelectronic applications. While still primarily in research and development phases, this material is being investigated for transparent conducting oxide (TCO) applications, gas sensing devices, and photocatalytic systems, where its crystal structure and electronic properties offer potential advantages over conventional semiconductors in high-temperature or chemically demanding environments. Its significance lies in the exploration of tin-based perovskites as alternatives to traditional oxide semiconductors, particularly for applications requiring environmental stability and tunable electrical characteristics.
