中文摘要: Pb(Mn1/3Sb2/3)O3-modified (≤4mol%) ferroelectric ceramics 0.5Pb(Ni1/3Nb2/3)O3-0.14PbZrO3-0.36PbTiO3 were successfully fabricated by the solid-state reaction method to investigate its influences on the phase structure and piezoelectricity as well as mechanical properties. The addition of Pb(Mn1/3Sb2/3)O3 (PMS) led to a phase transformation from tetragonal to rhombohedral and a slightly increased average grain size. The compositions modified by PMS mainly displayed "harden" effect, accompanying with the increase of mechanical quality factor Q m and internal bias field E i . The mechanical properties of the ceramics were strengthened monotonously with the addition of PMS, while the piezoelectric coefficient showed a peak value of d 33 *~1058pm/V when the PMS content equaled to 1mol%. Fairly good electrical properties and mechanical performance of d 33 *~1036pm/V (E=1kV/mm), planar electromechanical coupling factor k p ~0.53, dielectric loss (1kHz)~0.4%, Young's modulus E~120.8GPa, fracture toughness K Ic ~1.44MPam1/2 were achieved in the sample with the addition of 2mol% PMS, which makes it promising for applications in piezoactuators, transducers and sensors. © 2015 Elsevier Ltd and Techna Group S.r.l.
