· JVASP-112676· K4BaNb5O15

K4BaNb5O15 is a potassium barium niobate ceramic compound belonging to the tungsten-bronze family of oxides, known for its complex perovskite-derived crystal structure. This material is primarily investigated in research contexts for ferroelectric and piezoelectric applications, where its ability to exhibit electrical polarization and mechanical coupling makes it relevant for sensor and actuator development. Compared to more conventional piezoceramics like lead zirconate titanate (PZT), tungsten-bronze niobates offer potential advantages in specific high-temperature or specialized electromechanical applications, though they remain less widely commercialized in mainstream engineering.
