|Abstract:||© 2019, © 2019 Taylor & Francis Group, LLC. In this research, Bi0.485(Na0.388K0.097)Ba0.021Sr0.009TiO3 or BNKBSrT ceramic sintered at various temperatures from 1100 °C to 1150 °C were investigated. The optimum density (5.80 g/cm3), mechanical (HK = 5.3 GPa, HV = 4.1 GPa, E = 62 GPa, and KIC = 1.35 MPa m1/2), dielectric (εr = 1525, tanδ = 0.0566), piezoelectric (d33 = 172 pC/N, g33 = 12 × 10−3Vm/N), electric field-induced strain (Smax = 0.32%, d*33 = Smax/Emax = 640 pm/V, Q33 = 0.0340 m4/C2), and energy storage (W = 0.55 J/cm3, η = 67.2% @ 150 °C) were obtained for the ceramic sintered at 1125 °C.|
