Abstract
A ceramic material has the following composition: (BaM)O.z(TiM)O.D.E. In this composition, (BaM)=A and (TiM)=B, where Mstands for at least one element selected from: Mg, Ca, Sr, Pb and mixtures thereof; Mstands for at least one element selected from: Sn, Zr and mixtures thereof; D stands for at least one element having donor properties; E stands for at least one element having acceptor properties. The following applies for the parameters: 0≦x≦0.6; 0≦y≦0.35; 0≦d≦0.02; 0≦e≦0.02; 1<z; and the following applies for the molar ratio of B to A: 1<B/A. The ceramic material comprises Si only as an impurity.
