Abstract:
Reduced and internally biased oxide wafer(RAINBOW)Pb(Sn, Zr, Ti)O3(PSZT)antiferroelectric ceramics are fabricated by chemical reduction. It is a new kind of large displacement actuating materials composed of reduced and unreduced layers. It is found that PSZT is easily reduced and the optimal conditions for producing RAINBOW samples are determined to be 870℃ for 2 to 3 h, which results in a reduced layer composed of metallic lead and refractory oxides(PbO, ZrO2 and ZrTiO4). The phase transitions from antiferroelectric state to ferroelectric state occur at lower field strength in RAINBOW samples compared with normal PSZT ceramics. Larger axial displacement is also obtained from RAINBOW samples by application of electric fields exceeding the phase switching level. However, the actuating properties of RAINBOW samples are dependent on the manner of applying load on it.
通过化学还原的方法制备了RAINBOW Pb(Sn, Zr, Ti)O3(PSZT)反铁电陶瓷. 它是一种具有还原层和未还原层、 驱动位移极大的新型驱动材料. 研究表明: PSZT反铁电陶瓷较易还原, 理想的还原条件为870 ℃保温2~3 h; 还原层主要由金属铅以及PbO, ZrO2, ZrTiO4等金属氧化物组成; 与普通的反铁电驱动器相比, RAINBOW试样能在强度较低的电场下发生反铁电-铁电相变, 并能得到极大的轴向驱动位移, 但加载方式对其驱动性能有决定性的影响作用.
