Glass ceramic having a specified relative permittivity used in the production of electrical components comprises a ceramic material, and a glass material containing a boron oxide, a silicon oxide, a divalent metal oxide, and a bismuth oxide

摘要

Glass ceramic having a relative permittivity of 600-10,000 comprises at least one ceramic material, and at least one glass material containing at least one oxide with boron, at least one oxide with silicon, and at least one oxide with at least one divalent metal Me2+. The glass material also has at least one oxide with bismuth. An Independent claim is also included for an electrical component (5) comprising the above glass ceramic. Preferred Features: The divalent metal is beryllium, magnesium, calcium, strontium, barium, copper and/or zinc.
