ABSTRACT:
A composite body made of at least two ceramic layers, in which the ceramic layers are permanently bonded to one another at defined bonding points by a contact layer made of a bonding material. To achieve a permanent, thermally stable bond of ceramic layers having different coefficients of thermal expansion, the bonding material has a low modulus of elasticity. During the manufacture of the composite body, the bonding points of the ceramic layers are pretreated to form a porous surface structure, the bonding material is applied to these bonding points, and after the ceramic layers are laid one on top of another with bonding points facing toward one another and bonding material lying between them, the assembled composite body is subjected to a heat treatment.
