A ceramic mixed system is proposed that includes a two-phase mixture of pure components A and B, wherein phase A is based on the cubic to tetragonal modification of Bi3NbO7 and phase B is based on a monoclinic pyrochlore modification of Bi2(Zn2/3Nb4/3)O7. The electrical properties of ceramics produced therefrom make the material suitable for components having a multilayer structure in which capacitors and inductors are integrated and which can be used in data processing or signal processing.

An X-ray tube includes a vacuum-filled housing and an anode contained in the vacuum-filled housing. The anode is operable to produce an X-ray beam based on electrons emitted from a cathode and attracted by a high voltage applied to the anode. The X-ray tube also includes a high-voltage power line introduced from an external side of the housing for supplying the anode with a high-voltage potential. The X-ray tube includes an electrical feed for electrically insulating the high-voltage power line from the housing. The electrical feed in the X-ray tube includes at least two insulating layers radially between the high-voltage power line and the housing. The at least two insulating layers are separated from one another by a metallic coating.
