Abstract
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.
