A metal-ceramic composite material has a ceramic matrix and at least one metallic phase, which are intermingled with one another, together forming a virtually completely dense body, and which are in contact with one another at boundary surfaces. The boundary surfaces are of acicular form, and the metallic phases and the ceramic matrix intermesh by means of the acicular boundary surfaces. Furthermore, tubular passages, which are filled by at least one metallic phase, pass through the composite material.
