Estimating the term…
The invention relates to a process for producing a metal-ceramic substrate (1), comprising: providing a ceramic element (10) and a metal layer, providing a gas-tight container (25) that encloses the ceramic element (10), the container (25) preferably being formed from the metal layer or comprising the metal layer, forming the metal-ceramic substrate (1) by connecting the metal layer to the ceramic element (10) by means of hot isostatic pressing, wherein, for the purpose of forming the metal-ceramic substrate (1), an active metal layer (15) or a contact layer comprising an active metal is arranged at least in some sections between the metal layer and the ceramic element (10) for supporting the connection of the metal layer to the ceramic element (10).
1-12. (canceled)
A method for producing a metal-ceramic substrate (1) comprising:
The method according to one of the preceding claims, wherein a proportion of active metal in the contact layer is greater than 25 wt. %.
The method according to claim 24, wherein the active metal layer (15) is subjected to an energy input prior to hot isostatic pressing.
The method according to claim 27, wherein, for forming the metal-ceramic substrate (1), an active metal layer (15) and a contact layer comprising an active metal is at least sectionally arranged between the metal sheet and the ceramic element (10) to promote metal sheet bonding to the ceramic element (10).
