Abstract

The piezoelectric properties of bismuth layer-structured ferroelectrics Nao_0-5-xBi_0.5+x/3Bi₂Ta₂O₉ (NBT(x)) dense ceramics were investigated, and the crystal structure of synthesized NBT(x) powders was analyzed by the Rietveld method. NBT(x) powder and ceramics were prepared by conventional synthesis method. NBT(x) powder for x=0 and x=0.1 was confirmed to be single phase of BLSFs (m=2) by x-ray diffraction method. The electromechanical coupling coefficients k_p of NBT(x=0) and NBT(x=0.1) dense ceramics were 10% and 8.3%, respectively. The k_p of NBT(x=0) was one of the largest in reported non-oriented BLSFs ceramics.
