ceramic

· JVASP-57814· K2YNb5O15

K2YNb5O15 is a potassium niobate ceramic compound belonging to the family of complex metal oxides with potential ferroelectric or piezoelectric properties. This material is primarily of research and developmental interest rather than established in high-volume industrial production, studied for its crystal structure and functional characteristics in advanced ceramic applications. The niobate family is notable for applications requiring high dielectric strength, piezoelectric response, or ferroelectric behavior at elevated temperatures, making it relevant for engineers exploring alternatives to traditional lead-based ceramics or conventional piezoelectric materials.
