Optimization Strategies for Boosting Ceramic Materials Based on Sodium Niobate

Published: Jan. 1, 2024

Abstract: Lead-free antiferroelectric (AFE) ceramics based on sodium niobate (NaNbO3, NN) have drawn garnered interest due to their remarkable energy storage capacity. However, The practical applications of pure NN been largely constrained by high loss density (Wloss) and low breakdown electric field (Eb) resulting from the field-induced AFE-ferroelectric (FE) phase transition. To address these issues, Bi Ti were introduced into A- B-sites ceramic chalcogenide structure, respectively. After that, Ta element was doped B-site (Na0.86Bi0.14)(Nb0.9Ti0.1)O3 samples, which effectively improved capacity ceramics. Finally, good properties (with Wrec approximately 2.41 J·cm-3 an efficiency about 90.88%) (Na0.86Bi0.14)(Nb0.75Ta0.15Ti0.1)O3 obtained via compositional modification under conditions a (Eb = 206.92 kV·cm-1). Therefore, results this study reveal that introduction tantalum is vible method improve dielectric
