METHOD FOR THE PRODUCTION OF METAL-CERAMIC COMPOSITE MATERIALS, ESPECIALLY METAL-CERAMIC SUBSTRATES AND CERAMIC COMPOSITE MATERIAL PRODUCED ACCORDING TO SAID METHOD, ESPECIALLY A METAL-CERAMIC SUBSTRATE.

摘要

The invention relates to a method for the production of metal-ceramic composite materials, especially metal-ceramic substrates, wherein a wafer-like ceramic substrate and an oxidized metal film are used as joining elements and are connected to each other by direct bonding by heating them to a process temperature in a protective gas atmosphere. The joining elements are placed in a reaction chamber formed inside a capsule. Said reaction chamber is separated from the outer protective gas area by the capsule or the contact thereof with the outer protective gas atmosphere occurs exclusively via a small opening section.
