Abstract
K<sub>0.5</sub>Na<sub>0.5</sub>NbO<sub>3</sub> (KNN)-based ceramics, as promising candidate materials that could replace lead-based ceramics, exhibit outstanding potential in pulsed power systems due to their large dielectric constant, high Curie temperature and environmental friendliness.
