© 2018 Elsevier Ltd Properties of lead-free Bi0.5-xLaxNa0.40K0.10Ti0.98Zr0.02O3(x = 0.000–0.040) ceramics were investigated. All ceramics have a pure perovskite structure. A high energy storage density (∼1.00 J/cm3) at room temperature (RT) is noted for the x = 0.030 sample, while x = 0.020 and 0.04...

All ceramics have a pure perovskite structure. A high energy storage density (∼1.00 J/cm3) at room temperature (RT) is noted for the x = 0.030 sample, while x = 0.020 and 0.040 samples have very high thermal stability of energy storage density of ∼3% (at 75–150 °C). Furthermore, the x = 0.030 and 0.040 samples have the highest energy storage efficiency (η) value of 94% at 125 °C with high thermal stability (η = 84–95% at 25–150 °C). The x = 0.005 sample has high electric field-induced strain (Smax= 0.42%) and high normalized strain coefficient (d*33= Smax/Emax= 700 pm/V) with large improvements (∼200% and 163% for Smaxand d*33, respectively), as compared to the based composition. This ceramic system has potentials for piezoelectric and/or energy storage density applications. 2018-09-05T04:30:51Z 2018-09-05T04:30:51Z 2018-09-01 Journal 1873619X 09552219 2-s2.0-85046347705 10.1016/j.jeurceramsoc.2018.04.024 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85046347705&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/58780
