Effect of calcia additions on the electromechanical properties of samarium-modified lead titanate ceramics

Modified lead titanate ceramics with a composition of (Pb/sub 0.88-x/Ca/sub x/Sm/sub 0.08/)(Ti/sub 0.98/Mn/sub 0.02/)O/sub 3/; 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 k/sub t/'s /spl ges/57%.
