Abstract

A method produces a component having a ceramic base body and contact surfaces on opposite sides of the ceramic base body. The method includes forming first protective layers on the opposite sides of the ceramic base body in regions not to be covered by the contact surfaces, forming second protective layers on opposite surfaces of the ceramic base body, sintering the ceramic base body with the first and second protective layers at a first temperature, forming the contact surfaces on the ceramic base body, and sintering the contact surfaces at a temperature that is lower than the first temperature.
