Enhanced energy-storage performance and electric-field-induced strain in Ta-doped (Bi0.465Na0.465Ba0.07)TiO3 lead-free ceramics
The influence of Ta5+ substitution on lead-free (Bi0.465Na0.465Ba0.07)TaxTi(1–x)O3 (BNBT–xTa, x = 0.0 to 0.03) ceramics was investigated. The samples were prepared using a conventional solid-state route, resulting in a phase-pure perovskite structure with pseudocubic characteristics for all compositions. With increasin...
