ceramic

· JVASP-53229· KCaNb2O6F

KCaNb2O6F is a mixed-metal oxide fluoride ceramic compound belonging to the niobate family, combining potassium, calcium, and niobium with fluorine substitution. This material is primarily of research interest for photonic and electrochemical applications, where the fluorine-doped niobate structure offers potential advantages in ion conductivity, optical properties, or catalytic behavior compared to conventional niobate ceramics. The fluorine incorporation is notable for modifying the crystal structure and defect chemistry, making it a candidate material for solid electrolytes, optical waveguides, or functional ceramic coatings in emerging technologies.
