Phase Transition and Electrical Properties of Ba0.7Ca0.3TiO3-BiFeO3 Ceramics

Lead‐free piezoelectric ceramics of (1 − x)Ba0.70 Ca0.30TiO3–xBiFeO3 [(1 − x)BCT–xBF, x = 0–0.065] have been prepared and investigated. The ceramics with x ≤ 0.06 have diphasic tetragonal and orthorhombic crystal structures, whereas tetragonal phase is suppressed by the introduction of BF. As a resu...
