In this research, (1-x)(Ba0.9Sr0.1)TiO3-xBi(Mg2/3Nb1/3)O3 (BST-BMN, where x = 0, 0.06, 0.08, 0.12 and 0.20) powders were synthesized via a solid-state reaction method. The corresponding lead-free ceramics obtained at the optimal sintering temperature. For ? material formed dense, homogeneous pseudocubic perovskite structures. increase of BMN content induces strong relaxor behaviours with diffuse phase transition characteristics, enhancing temperature stability dielectric properties. Consequently, exhibited narrow polarization-electric field (P-E) loops superior energy storage capabilities. composition 0.88BST-0.12BMN was found to be optimal, attributed improvement in breakdown strength, yielding recoverable density 2.504 J/cm3 an efficiency 90.2%under electric strength 250 kV/cm. Furthermore, ceramic retains consistent across temperatures ranging from 20 120?C frequencies 1 100Hz, underscoring its potential for application high-power pulsed capacitors.

Abstract The burgeoning requirement for compact electronic devices has intensified research into lead‐free dielectric ceramics that offer superior recoverable energy storage density and efficiency at low electric fields. In this study, we report the synthesis of Nd 3+ ‐doped (Bi 0.4 K 0.2 Na Sr )TiO 3 perovskite via solid‐state reaction technique. synthesized adopted a tetragonal crystal structure. As concentration ions increased, both maximum constant ( ε m ) its corresponding temperature T decrease. incorporation perturbed long‐range ferroelectric order, leading to diminished polarization P remanent r ). achieved optimal properties with 12 mol% doping, showcasing significant 1.50 J/cm field 140 kV/cm, along an exceptional 94.6%. This not only highlights promising candidate materials in applications but also introduces innovative approach enhance performance.

Abstract High‐entropy perovskite ceramics have garnered widespread attention in the energy storage field due to their diversified composition and superior performance. However, preparation of high‐performance high‐entropy ceramic materials still faces many challenges complex structure. This work systematically studies effects MgO, SiO 2 , Li CO 3 MnCO on sintering temperature performance (Na 0.2 Bi Ba Sr Ca )TiO (NBBSCT) ceramics. The introduction successfully reduced 1150°C achieved a high efficiency 95.5% with this composition. NBBSCT 0.5 wt%MgO exhibited breakdown 300 kV/cm an density 3.7 J/cm . study indicates that adding appropriate aids can significantly improve behavior method provides new insights into enhancement
