Abstract

The preparation and characterization of multilayer actuators with fifty layers (100 μm in thickness) of piezoelectric [(Pb_(1-x/)Basub x/)_6-y(NaLi)_yNb₁₀O₃₀] (PBNN) were reported, which were prepared by tape-casting and cofired with internal Pd30+Ag70 electrodes. The PBNN wafers prepared by the tape-casting technique were compared with those prepared by conventional dry-pressure techniques. Delaminations occurring in the layers of some actuators were observed and discussed. The obtained high linearity and low hysteresis in the displacement-applied field, the symmetric displacement under positive and negative applied field, were discussed in relation to the crystal and domain structure
