Calcium germanate (CaGeO3) is an inorganic ceramic semiconductor compound combining alkaline earth and group IV elements in a perovskite-like crystal structure. This material remains primarily in research and development phases, with potential applications in photonic devices, scintillation detectors, and wide-bandgap optoelectronic components where its semiconductor properties could enable UV-sensitive or radiation-detection functionality. Its selection would be driven by specialized optical or radiation-sensing requirements where the calcium-germanate system offers advantages in transparency, thermal stability, or detection efficiency compared to conventional semiconductors, though commercial availability and manufacturability are currently limited.
