摘要：
(1-x)(Bi(0.9)Li(0.10))(Sc(0.90)Ta(0.10))O(3)-xPbTiO(3) (BLSTPTx; x = 0.06-00.65) ceramcis wer prepared using the conventional mixed oxide method. X-ray diffrection analysis revealed that BLSTPTx has a pure perovskite structure. In the vicinity of the morphotropic hase boundary, which was observed in the compositional range 0.61 <= x <= 0.62 from phase structure measurements the BLSTPT ceramics showed enhanced piezoelectric properties piezoelectric constant d(33) = 516 pC/N, planar electromechanical coupling factors k(p) = 57%. The temperature measurement frequency over the range 302-313 degrees C, higher than that of conventional relaxor materials such as Pb(B(1)B(2))O(3) PbTiO(3) systems. The ceramics show relaxor ferroelectric features. (C) 2010 WILEY-VCH Verlag GmBH & Co. KGaA, Weinheim.
