Effect of BiAlO3 concentration on the dielectric and piezoelectric properties of lead-free (Bi0.5Na0.5)0.94Ba0.06TiO3 piezoelectric ceramics

Enhanced ferroelectric properties and thermal stability of Mn‐doped 0.96(Bi0.5 Na0.5)TiO3‐0.04BiAlO3 ceramics

“…Nevertheless, the addition of BiAlO 3 leads to a decrease in the depolarization temperature T d . Detailed knowledge of the phase structure and electrical properties of BNT–BA ceramics has been presented in the literatures . The temperature‐dependent electrical properties and in situ TEM study of BNT‐based ceramics indicate that T d corresponds to the transition from ferroelectric (FE) phase to anti‐ferroelectric (AFE) phase .…”

Multilayer lead‐free piezoceramic composites: Influence of co‐firing on microstructure and electromechanical behavior

“…In the heterogeneous case of 2‐2 composites, Al depletion in the matrix phase would result in the formation of (100‐ x )BNKT‐ x BA, where x <3 mol% results in a non‐ergodic relaxor with high remanent polarization . BNKT‐1.5BA and BNKT have been used as seed material in composite systems, where BNKT‐6BA is the matrix, resulting in a lower poling field and higher strain response .…”

Structure and electrical properties of Bi1/2Na1/2TiO3-based lead-free piezoelectric ceramics

“…21 Consequently, a host of studies have been made in which BiAlO 3 has been used as an addition to enhance the performance of BNT-based in the form of solid solution. 22 The results implied that BNT-based ceramics with BiAlO 3 -doping could be excellent lead-free candidates for ferroelectric material. Yu et al have synthesized and studied BNT-BiAlO 3 solid solution.…”
