The invention proposes a paste for welding ceramic materials to metallic contact surfaces or metals, which contains a noble metal, an aluminum compound, a silicon compound, and a compound selected from the group of the barium compounds, calcium compounds, and magnesium compounds. Along with these, a binder, a solvent, a softener, a thixotropic agent, and a dispersing agent can also be added to the paste. A paste of this kind is used to produce a welded joint between ceramic materials and a metallic contact surface, the paste preferably being printed onto the ceramic material. The ceramic material is then sintered with the paste, and then the metallic contact surface or a metal is welded on.
