摘要：
The ceramics with the formula of (1-y)[0.995Bi(0.5)(Na0.80K0.20)(0.5)TiO3-0.005LiNbO(3)]-yBa(Ti0.90Sn0.10)O-3 or (1-y)[0.995BNKT-0.005LN]-yBTS (y = 0-0.05 mol fraction) were successfully prepared by a conventional mixed oxide method. It was found that all compositions showed single phase with a mixed rhombohedral/tetragonal structure. The highest piezoelectric coefficient (d(33) = 175 pC/N) with good dielectric (epsilon(r) = 1775, tan delta = 0.0534) and ferroelectric properties (P-r = 12.33 mu C/cm(2), R-sq = 1.37) was obtained for y = 0.04 sample. The bipolar S-E loops showed highest S-max = 0.25% at y = 0.05.
