A ceramic mass includes one ceramic material and at least a second different ceramic material. Glass material is arranged between the ceramic materials. The glass material reduces the sintering temperature of the ceramic mass and prevents the various ceramic materials from forming a mixed crystal when the ceramic mass is sintered. The ceramic mass is suitable for use in LTCC technology for the production of capacitors whose permittivity is dependent upon a specific temperature range.

Ceramic mass, method for the production of a ceramic mass and use of a ceramic mass

The invention is directed to an extremely low-capacitance device for shaping an electron beam. The device is based on a ceramic body having a monolithic multi-layer structure. The manufacture of the ceramic body ensues with the assistance of LTCC technology, whereby this method is designationally modified. The body is constructed of pre-sintered ceramic layers whose lateral shrinkage is suppressed. The through apertures of the electrodes for the electron beam are thus arranged exactly coaxially, and the tolerances of the electrode dimensions are decoupled from the shrinkage during sintering. The electron beam of an electron gun is focused and the intensity thereof is modulated with the assistance of such a device.
