| Abstract: | The Ba0.96Ca0.04Ti0.90Sn0.10O3-xNd2O3 (x = 0–0.08%) ceramics were prepared via traditional solid-state sintering method. The influences of Nd3+ substitution on the phase structure, dielectric properties, piezoelectric and ferroelectric properties of the ceramics were investigated. All the samples possess pure BaTiO3-type perovskite structure. MPB with orthorhombic and tetragonal phase coexist at around x = 0.03–0.04. Nd3+ doping decreases both Tc and TO–T to lower temperature. All the samples exhibit an intermediate state with the coexistence of ferroelectric and diffuse relaxor ferroelectric behavior with the addition of Nd3+. The electric properties of the ceramics were optimized at x = 0.03 with d33, Kp, ?r and Pr values of 545 pC/N, 51.9%, 24,412 and 10.74 μC/cm2. |
