| dc.description.abstractEn | New lead free ceramics derived from the ferroelectric material BaTiO<sub>3</sub> by substituting Ti<sup>4 +</sup> by Nb<sup>5 +</sup> and Yb<sup>3 +</sup>. The dielectric and ferroelectric properties were studied. The compositions BaTi<sub>1 - <i>x</i></sub>(Nb<sub>0.5</sub>Yb<sub>0.5</sub>)<sub><i>x</i></sub>O<sub>3</sub> display a classical ferroelectric (0 ≤ x < 0.1) and relaxor ferroelectric behaviour (0.1 ≤ x ≤ 0.2). BaTi<sub>0.9</sub>(Nb<sub>0.5</sub>Yb<sub>0.5</sub>)<sub>0.1</sub>O<sub>3</sub> specimen present a relaxor behaviour at a temperature close to room with high permittivity (ε'<sub><i>r</i></sub> = 9500 at 1 kHz), which opens the way for possible use of it for capacitor applications. The polarisation hysteresis loops were observed of relaxor BaTi<sub>0.875</sub>(Nb<sub>0.5</sub>Yb<sub>0.5</sub>)<sub>0.125</sub>O<sub>3</sub> specimen. The ceramic BaTi<sub>0.9</sub>(Yb<sub>0.5</sub>Nb<sub>0.5</sub>)<sub>0.1</sub>O<sub>3</sub> provides a piezoelectric constant d<sub>31</sub> of about 11.17 pC/N near room temperature. | |
