<title>Abstract</title> Relaxor ferroelectric ceramics have emerged as promising candidates for electrocaloric cooling systems due to their relatively higher heating and capacities. However, simultaneously achieving high temperature changes (ΔT) a wide operating range remains significant challenge, limiting practical applications. This work proposes synergistic strategy that involves precise compositional tuning of the BaTiO₃-xKNbO₃ system customize rhombohedral-to-cubic phase boundary...
KNbO 3 doping is used to increase the relaxor degree, reduce remanent polarization, and improve energy storage performance.
<title>Abstract</title> Dielectric ceramics possess a unique competitive advantage in electronic systems due to their high-power density and excellent reliability. Na0.5Bi0.5TiO3 (NBT)-based ceramics, one type of extensively studied energy storage dielectric, however, often experience A-site element volatilization Ti4+ reduction during high-temperature sintering. These issues may result increased loss, reduced polarization low dielectric breakdown electric field (EB), ultimately making it...
