Ca2GeO4 is an inorganic oxide ceramic compound composed of calcium and germanium oxides, belonging to the family of germanate ceramics. This material is primarily investigated in research contexts for optical and photonic applications, particularly as a host material for rare-earth ion doping to create luminescent ceramics and phosphors. It is notable within the germanate ceramic family for its potential in scintillation detection, solid-state lighting, and thermal barrier coating systems where its chemical stability and refractory character offer advantages over more conventional oxide ceramics.
