Effects of Mn doping on electrical properties of BiFeO3–SrTiO3 solid solution

Microstructure, dielectric, and piezoelectric properties of BiFeO3–SrTiO3 lead‐free ceramics

“…35 Additionally, Lu et al prepared 0.6BF-0.4ST ceramics, which exhibited excellent electromechanical properties including P r ∼ 29.8 μC/cm 2 and electro-strain of ∼0.15%, indicating the presence of multi-symmetry polar nanoregions. [36][37][38] To optimize the piezoelectric properties of BF-ST ceramics, in this work, (1 − x)BF-xST (x = 0.32, 0.34, 0.36, 0.38, 0.40, 0.42, and 0.44) lead-free ceramics with MPB compositions were prepared by the conventional solid-state reaction method, 39 and the effects of composition variation of BF-ST on the phase structure, microstructure, dielectric, and piezoelectric properties were systematically investigated.…”
