Abstract

The piezoelectric material composition is PZT-SKN with a Li ₂CO₃ flux. This system has been developed successfully for air-fired actuators in PSU with Ag-Pd alloyed inner electrodes. We tried to control the lead activity by adding higher excess PbO in the formulation. Samples were all sintered at 900°C for 6 hours in PO₂ = 5.38×10^-12 atm. With 3.0, 4.0wt% PbO excess addition, we note that density, micro-structure and permittivity are similar and there is a high electro-mechanical performance for example, the high field piezoelectric d ₃₃ was ∼480pm/V. However, there is some decrease in d ₃₃ after the sintering in low PO₂ and Rayleigh coefficients shows PO₂ to slightly suppressing both the intrinsic and extrinsic contribution to piezoelectric properties. Multilayer actuators with copper inner electrode were successfully fabricated with the PZT-SKN after processing with techniques and materials that have low residual carbon.
