Abstract

A relaxor ferroelectric material, Pb(Mg_1/3Nb_2/3) O₃ (PMN) powder with a pyrochlore-free phase, was prepared by using a one-step calcinations method. The pyrochlore phase was prevented by coating Mg(OH)₂ on Nb₂O₅ particles. Pure-perovskite PMN powder was synthesized by a single calcination of the coating powder mixed with appropriate amounts of PbO at 900°C for 2 h. The pyrochl ore-free perovskite PMN powders were sintered to 96.9% density at 100°C. The sintered PMN ceramics exhibited a dielectric constant maximum of ∼11 700 at room temperature at a frequency of 1 kHz.
