COMPOUND OXIDE POWDER COMPOSITION, SINTERED MATERIAL THEREOF AND PRODUCTION THEREOF

摘要

PURPOSE:To improve a dielectric constant, by excessively adding a Mg component and a Ni component to specific compound oxide powder. CONSTITUTION:A powder composition containing Pb(Mg1/3Nb2/3)O3Pb(Ni1/3Nb2/3) O3 (PMN-PNN for short)-based compound oxide powder, a Mg component and an Ni component is obtained by sintering. The powder composition contains more excessively the Mg component and the Ni component than a stoichiometric amount constituting PMN-PNN-based compound oxide.
