文摘

(1???em class="a-plus-plus">x)(Na0.5Bi0.5)0.94Ba0.06TiO3-em class="a-plus-plus">xSmAlO3 [(1???em class="a-plus-plus">x)BNBT6-em class="a-plus-plus">xSA] lead-free piezoelectric ceramics were synthesized by conventional solid-state method. Effects of composition on the micro-structure and electrical properties of (1???em class="a-plus-plus">x)BNBT6-em class="a-plus-plus">xSA ceramics were investigated. X-ray diffraction data shows that (1???em class="a-plus-plus">x)BNBT6-em class="a-plus-plus">xSA ceramics form the pure perovskite phases, and the ceramics have the morphotropic phase boundary when x?≤?.0100. At room temperature, the electrical properties of the BNBT6 ceramics have been improved with the addition of appropriate SA. At room temperature, (1???em class="a-plus-plus">x)BNBT6-em class="a-plus-plus">xBA ceramics at x?=?0.0100 has the highest remnant polarization (P r?=?47?μC/cm2), the highest piezoelectric coefficient (d 33?=?179?pC/N), the highest planar coupling factor (k p?=?0.296), the higher dielectric constant (? r?=?1154) and higher mechanical quality factor (Q m?=?131).
