Abstract
(Na0.5Bi0.5)TiO3 doped with 5 mol% BaTiO3 (NBT-BT0.05) nanopowder was prepared by sol–gel method. Structural and microstructural investigations revealed a powder crystallized in the Na0.5Bi0.5TiO3 rhombohedral phase form. Ceramics processed from this powder show good dielectric (ɛr = 3940 and tan δ = 0.016) and piezoelectric characteristics (d33 = 77 pC/N, kp = 0.091, ε 33 T = 1080 and Qm = 197.5). The as-obtained NBT-BT0.05 ceramic appears effective for piezoelectric resonator and high power applications.
