Abstract Bi0.4806-xYbxNa0.4606Ba0.0588Ti0.98Al0.02O3 (x = 0.0, 0.005, 0.01, 0.05) ceramics were processed using a solid state sintering route. Highly dense microstructure with maximum apparent density was obtained for the composition of x = 0.005. The polarization versus electric field (P-E) loop got relatively slimmer and remnant polarization decreased with an increase in x content. A maximum recoverable energy density of 0.69 J/cm3 at a DBS of 95 kV/cm was obtained at x = 0.005 with its dielectric constant satisfying the condition of Δer/er200°C ≤ ±15% in a working temperature range of 97 to 383 °C having

摘要 Bi0.4806-xYbxNa0.4606Ba0.0588Ti0.98Al0.02O3 (x = 0.0, 0.005, 0.01, 0.05) 陶瓷采用固态烧结工艺进行加工。对于 x = 0.005 的组成，获得具有最大表观密度的高致密微观结构。随着 x 含量的增加，极化与电场 (PE) 回路变得相对更薄，剩余极化减少。在 95 kV/cm DBS 下，在 x = 0.005 下获得了 0.69 J/cm3 的最大可恢复能量密度，其介电常数满足 Δer/er200°C ≤ ±15% 的条件，工作温度范围为 97 至 383 °C 有
