Abstract

The piezoelectric properties of the cobalt-modified sodium bismuth titanate (Na_0.5Bi_4.5Ti₄O₁₅, NBT) piezoelectric ceramics were investigated. The piezoelectric properties of NBT ceramics were significantly enhanced by cobalt modification. The Curie temperature T_C and piezoelectric constant d₃₃ for the 0.3 wt% cobalt-modified NBT ceramics (NBT-C3) were found to be 663 °C and 30 pC/N, respectively. Thermal annealing studies presented that the cobalt-modified NBT ceramics possess stable piezoelectric properties, demonstrating that the cobalt-modified NBT-based ceramics are promising candidates for high temperature piezoelectric applications.
