· JVASP-57054· KNaTiO3

KNaTiO3 is a mixed-alkali titanate ceramic compound combining potassium, sodium, and titanium oxides into a perovskite-related structure. This material is primarily investigated in research contexts for ferroelectric and piezoelectric applications, where the dual-alkali composition can influence polarization behavior and dielectric response. Industrial adoption remains limited, but the material family shows promise in capacitive devices, sensing elements, and electro-optic applications where the interplay between potassium and sodium cations can tune functional properties beyond single-alkali titanates.
