Relaxor Ferroelectric Ceramics

In this work, we report the dielectric and ferroelectric properties of CuO-doped ([Formula: see text])[0.5573Pb(Mg[Formula: see text]Nb[Formula: see text])O3-0.4427PbTiO3]-[Formula: see text]Ba(Zn[Formula: see text]Nb[Formula: see text]O3 (PMNT-[Formula: see text]BZN) relaxor ferrielectric ceramic samples with [Formula: see text], 0.1925, 02125 and 0.2325, which were fabricated by a conventional solid-state reaction method. By introducing the CuO into PMNT-[Formula: see text]BZN, the sintering temperature of this system is drastically lowered from 1280∘C to 1120∘C. The second pyrochlore phase, which is often generated during sintering at high temperature, is also inhibited. Meanwhile, broad dielectric peaks with strong dielectric relaxation characteristics are observed from [Formula: see text]C to 100∘C. Slim and slanted [Formula: see text]-[Formula: see text] hysteresis loops and purely electrostrictive strains with V-shape are obtained simultaneously in studied compositions from 30∘C to 150∘C. These results suggest that CuO could effectively lower the sintering temperature while maintaining the dielectric and ferroelectric properties of PMNT-[Formula: see text]BZN relaxor ferroelectric ceramics.
