TLDR
In this paper, an inner ceramic layer, an outer metal layer and an intermediate interface layer of a low modulus metallic low density structure having a high melting point are secured by an intermediate ceramic-metal composite.Abstract:Â
A ceramic-metal composite laminate capable of exposure to high temperature differentials without damage, consisting of an inner ceramic layer, an outer metal layer and an intermediate interface layer of a low modulus metallic low density structure having a high melting point. The ceramic layer is secured to the low modulus structure directly or through an intermediate ceramic-metal composite, and the outer metal layer is brazed to the intermediate low modulus layer. Thermal strains caused by a temperature differential between the inner and outer layers are taken up without harmful effect by the intermediate low modulus layer.read more

Glass frit-ceramic powder composition
TL;DR: In this article, a technique for fabricating metal-ceramic articles wherein a hermetic seal is desired between the metal andceramic jointure is described. But the technique involves utilization of a powdered ceramic containing a binding material which is compressed in a mould around the metal part or parts to be incorporated therein.
