High‐Entropy La‐(Bi0.2Na0.2Ba0.2Sr0.2Ca0.2)TiO3 Ceramic with Ultrastable Dielectric Performance within 327–689 K and up to 7 GPa

High‐Entropy La‐(Bi0.2Na0.2Ba0.2Sr0.2Ca0.2)TiO3 Ceramic with Ultrastable Dielectric Performance within 327–689 K and up to 7 GPa

Abstract To meet the needs of energy storage under high temperature and high pressure, a high‐entropy relaxor ferroelectric ceramic, La‐modified (Bi0.2Na0.2Ba0.2Sr0.2Ca0.2)TiO3 is prepared, which has excellent thermal and mechanical stability. At the wide temperature range of 327–689 K (tan δ < 0...
