· KNb2O5

KNb2O5 is a potassium niobate ceramic compound belonging to the family of niobium oxides, which are refractory and electroceramics materials. This compound is primarily investigated in research contexts for ferroelectric, piezoelectric, and optical applications, leveraging niobium's strong polarizability and the structural stability imparted by potassium incorporation. While not yet widely deployed in high-volume industrial production, potassium niobate ceramics are of interest as alternatives to lead-based ferroelectrics in emerging device technologies and as functional fillers in composite materials.
