摘要： A method of producing a piezostack device including multiple piezoelectric ceramic layers of a crystal-orientated ceramic and multiple electrode-containing layers laminated alternately. A raw material mixture is prepared in the mixing step, as an anisotropically shaped powder of oriented particles and a reactive raw powder are mixed. The anisotropically shaped powder and the reactive raw powder are then mixed in amounts at a stoichiometric ratio giving an isotropic perovskite compound, and a Nb2O5 powder and/or a Ta2O5 powder were added thereto. The raw material mixture is molded into a sheet shape in the sheet-forming step, while the crystal faces of the anisotropically shaped powder particles are almost oriented. An electrode material is printed on the green sheet in the printing step. The green sheets obtained after the printing step are laminated in the laminating step. The composite thus obtained is sintered in the sintering step, to give a piezostack device.

摘要： A laminate type dielectric device is formed by alternately laminating dielectric ceramic layers and electrode layers and integrally baking the laminate product. The electode layers are mainly made of an electrically conductive base metal material having greater standard Gibbs free energy for the formation of a metal oxide at a baking temperature than that of the ceramic material constituting the dielectric ceramic layers. Segregation of the materials including the electrically conductive base metal material does not occur at portions sandwiched between adjacent positive and negative electrode layers among the dielectric ceramic layers.
