Effect of Calcia Additions on the Electromechanical Properties of Samarium-Modified Lead Titanate Ceramics
Abstract
Modified lead titanate ceramics with a composition of (Pb0.88-xCaxSm0.08)(Ti0.98Mn0.02)O3; x = 0.11, 0.13, 0.15 and 0.17 were prepared. Simultaneous doping of samarium and calcium resulted in normal ferroelectric behavior, i.e. the dielectric properties changed in a manner typically associated with isovalent shifting of the Curie temperature. However, the unique attribute of this system appeared for the x=0.13 and 0.15 compositions, which exhibited kt's ≥75%.
