Piezoelectric properties of niobium doped Pb(ScNb)(1/2)O-3 :PbTiO3 [PS
N:PT] ceramics near the morphotropic phase boundary are investigated.
The piezoelectric coupling factors k(p) approximate to 82%, k(31) = 48
%, k(33) = 77%, and k(t)= 57% are measured. In good samples, values of
remanent polarization of 40.81 mu C/cm(2) and the mechanical quality
factor, Q(m) less than 10 show the potential of the material for desig
ning high sensitivity and wide bandwidth sensors and transducers. (C)
