Calcium titanate (CaTiO3) is a ceramic compound with perovskite crystal structure, classified as a semiconductor material. It is primarily used in electronic and photocatalytic applications, including dielectric substrates, photocatalysts for water splitting and environmental remediation, and ferroelectric device components. CaTiO3 is notable for its chemical stability, tunable bandgap through doping, and abundance of precursor materials, making it an attractive research-focused alternative to lead-based perovskites and other rare-earth ceramic semiconductors.
