摘要：
The piezoelectric properties of bismuth layer-structured ferroelectrics Na0.5-x,Bi0.5+x/3 Bi2Ta2O9 W3 (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 4 of NBT(x=0) and NBT(x = 0.1) dense ceramics were 10% and 8.3%, respectively. The 4 of NBT(x=0) was one of the largest in reported non-oriented BLSFs ceramics.
