CaSnO2 (calcium stannate) is an inorganic ceramic compound combining calcium and tin oxides, belonging to the perovskite-related oxide ceramic family. This material is primarily investigated in research and emerging applications for transparent conductive coatings, optoelectronic devices, and advanced gas sensing systems, where its oxide stability and electronic properties offer advantages in high-temperature or chemically aggressive environments. While not yet a mainstream engineering material, calcium stannate represents the broader class of tin-based oxide ceramics that show promise as alternatives to conventional indium-tin oxide (ITO) in applications requiring earth-abundant, cost-effective transparent conductors or functional ceramic layers.
