Enhanced piezoelectric properties of sodium bismuth titanate (Na 0.5Bi4.5Ti4O15) ceramics with b-site cobalt modification

Journal Article


Abstract


  • The piezoelectric properties of the cobalt-modified sodium bismuth titanate (Na0.5Bi4.5Ti4O15, NBT) piezoelectric ceramics were investigated. The piezoelectric properties of NBT ceramics were significantly enhanced by cobalt modification. The Curie temperature TC 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. �� 2009 WILEY-VCH Verlag GmbH&Co.
