Process for manufacturing ceramic metal composite bodies, the ceramic metal composite body and its use

摘要

A process for manufacturing a ceramic metal composite body in the case of which a dimensionally stable and porous sacrificial body is produced from ceramic initial products and is filled at a filling temperature with a softened metal, particularly under an increased pressure. The filled sacrificial body is heated to a reaction temperature and the metal to be filled in, BMe, is reacted with a metal of the ceramics. KMe, forming the ceramic metal composite body which has a ceramic phase having KMemBx and/or KMenCy and/or KMeoCN and BMepO3 and has a metallic phase having an intermetallic compound which is formed of KMe and BMe, the filling temperature being lower than the reaction temperature and higher than or equal to the softening temperature of the metal.
