摘要/描述

(1−x)Pb(Ni1/3Ta2/3)O3−xPbTiO3 (x=0.00-0.80) ceramics were prepared by the columbite/wolframite method. The phase stabilitywas studiedby XRD analysis. No perovskite phase was formed for x=0.00. As PT content increases in the solid solution, the perovskite phase becomesdominant at room temperature. When x≥0.60, a pure perovskite phase was obtained. The temperature dependence of the dielectric propertieswas evaluated. A maximum of the dielectric constant of about 28,000 is observed for x=0.60 ceramics.
