摘要：

(1 - x)Pb(Mg1/3Nb2/3)O-3-xPbTiO(3) (PMN-PT) ceramics with a: near morphotropic phase boundary (x=0.25 similar to 0.40) were prepared by Columbite technique. The influences of PT content and preparation process on dielectric, ferroelectric and piezoelectric properties were studied. The results show that ceramics with x between 0.32 and 0.35 possess higher dielectric constant, piezoelectric constant, coupling factor and lower mechanical figure of merite. The properties are comparable to best soft PZT ceramics.
