Resonance-antiresonance spectra (fundamental radial mode) of CBT-11GM measured at different temperatures

Caption

The electromechanic coupling behaviors of the poled CBT-11GM ceramics at high temperatures were measured in the frequency range of 20 Hz~2 MHz by an impedance analyzer associated with furnace. The resonance-antiresonance pair peaks tend to disappear at 700 ℃, indicating a thermal depoling behavior beginning from this temperature. Since the resonance-antiresonance spectra of the sample was in-suit measured at high temperature, this temperature can be viewed as the intrinsic thermal depoling temperature of the sample.
