Dielektrische Keramik, Keramikelektronikelement und Vielschicht-Keramikkondensator
Dielektrische Keramik mit:einer durch die allgemeine Formel:{BaCaSn)(TiZr)O} wiedergegebenen Perowskitverbindung als Hauptbestandteil;dadurch gekennzeichnet, dass x, y, z und munderfüllen.
A dielectric ceramic including a perovskite compound represented by the general formula {(Ba1-x-yCaxSny)m(Ti1-zZrz)O3} as a primary component in which the x, y, z, and m satisfy 0.02<=x<=0.20, 0.02<=y<=0.20, 0<=z<=0.05, and 0.99<=m<=1.1 and is processed by a thermal treatment at a low oxygen partial pressure of 1.0x10-10 to 1.0x10-12 MPa. Accordingly, there are provided a dielectric ceramic which can be stably used in a high-temperature atmosphere without degrading dielectric properties, properties of which can be easily adjusted, and which generates no electrode breakage even when ceramic layers and conductive films are co-fired, and a ceramic electronic element, such as a multilayer ceramic capacitor, which uses the above dielectric ceramic.
