摘要	The (Ba0.97-xCa0.03Dyx)(Ti0.98Mg0.02)O-3 (BCTDM-nano) (x=0, 0.005, 0.01, 0.02, 0.03) ceramics with nanosized grains were synthesized through a solid-state reaction method. The influence of Dy3+ substitution on the lattice and electrical properties were investigated. The X-ray diffraction and Raman scattering analyses demonstrate that the Dy3+ ions could modulate the doping position of Ca2+ and Mg2+ and affect the tetragonality and defects in BaTiO3 matrix. The maximum dielectric constant was increased up to 2500 for the sample with x=0.01. A high dielectric breakdown strength of 239kVcm(-1) was obtained at x=0.01. The high grain boundary resistance resulted from a charge compensation by Dy doping benefits the improved dielectric breakdown strength.
