· JVASP-59044· CaNb2O4

Calcium niobate (CaNb2O4) is an inorganic ceramic compound composed of calcium and niobium oxide, belonging to the family of mixed-metal oxides used in advanced ceramic applications. This material is primarily investigated for high-temperature and dielectric applications, including microwave dielectrics, optical coatings, and solid-state electrolytes in electrochemical devices. CaNb2O4 is notable for its potential thermal stability and dielectric properties, making it of interest in telecommunications, energy storage, and specialty refractories where conventional ceramics may fall short.
