Ceramic mass a capactor produced using a ceramic mass

摘要

The invention is directed to a ceramic comprising a phase-heterogeneous ceramic comprising m weight percent of a phase composed of BaNd2Ti4O12 with negative temperature coefficient of the dielectric constant and 100-m weight percent of a phase composed of Nd2Ti2O7 with positive temperature coefficient of the dielectric constant, whereby 50<m<70 applies, and comprising an additive of glass frit that contains ZnO, B2O3 and SiO2 and whose weight amounts to between 3 and 10 weight percent of the ceramic. The invention is also directed to a multi-layer capacitor having the ceramic mass. The inventive ceramic mass has the advantage that it can already be produced at a maximum calcination temperature of 1180° C. and that a minimization of the temperature coefficient of the dielectric constant is possible by means of a suitable selection of the parameter m. Over and above this, the inventive ceramic mass can be sintered together with copper electrodes.
