Abstract
A capacitor dielectric with inner blocking layers is disclosed wherein the portion of copper located in intermediate layers between the crystallites is enriched toward the crystallite surfaces. The dielectric is produced by a heating speed of 200 to 800.degree. C/h towards a sinter temperature, and a cooling-off speed of 10 to 100.degree. C/h to about 350.degree. C below the sinter temperature.
