发明名称 Multilayer capacitor
摘要 A capacitor comprises a number of ceramic layers on the basis of barium titanate as well as a number of electrode layers of palladium or a silver-palladium alloy, the ceramic layers and the electrode layers being alternately stacked to form a multilayer, which is also provided with two external electric connections which are in contact with a number of said electrode layers. In accordance with the invention, the electrode layers contain copper oxide, preferably 0.5-15 wt. %, calculated with respect to the overall quantity of palladium, silver and copper oxide. It has been found that the presence of a relatively small, yet effective quantity of copper oxide in the electrode material of Pd or Pd-Ag leads to a considerable increase of the internal mechanical strength and of the service life of CMCs. By employing the method in accordance with the invention, the percentage of rejects in the production of the capacitors can be reduced considerably.
