| Abstract: | (1 - x)Pb(Mg_1/3Nb_2/3)O_3-xPbTiO_3 (PMN-PT) ceramics with x near morphotropicphase boundary (x=0.25~0.40) 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 arecomparable to best soft PZT ceramics. |
