Abstract
A ceramic mass has a phase-heterogeneous ceramic of m weight percent of a phase composed of BaNdTiOwith negative temperature coefficient of the dielectric constant and 100-m weight percent of a phase composed of NdTiOwith positive temperature coefficient of the dielectric constant, with m having a value of 50<m<70, and an additive of glass frit that contains ZnO, BOand SiOand whose weight amounts to between 3 and 10 weight percent of the ceramic. The ceramic mass is used to construct a multi-layer capacitor with copper electrodes.
