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.
