Influences of a combination between the two-stage sintering and the reaction sintering techniques on phase formation, microstructure and dielectric properties of relaxor perovskite 0.93Pb(Zn1/ 3 Nb2/ 3 )O 3 -0.07BaTiO 3 or 0.93PZN-0.07BT ceramics were determined via X-ray diffraction, scanning electron microscopy and dielectric measurement techniques, respectively. Under suitable two-stage reaction sintering schemes, it was found that dense and pure perovskite 0.93PZN-0.07BT ceramics with fine grain size can be successfully achieved with better dielectric properties than those of ceramics from single-stage reaction sintering. © 2013 Copyright Taylor and Francis Group, LLC.
