Ceramic multi-layer component and method for the production thereof
Methods for producing a multilayer ceramic component with alternating ceramic layers and internal electrode layers include producing the ceramic layers using a ceramic mass. The methods also include producing the internal electrode layers using a metal paste that contains a portion of a chemically active additive; wherein the chemically active additive reacts chemically with at least one environmental component other than a metal portion of the metal paste.
1. A method for producing a multilayer ceramic component with alternating ceramic layers and internal electrode layers, comprising:
producing the ceramic layers using a lead-containing ceramic mass;
producing the internal electrode layers using a metal paste that contains a portion of a chemically active ceramic powder;
positioning the internal electrode layers and ceramic layers one on top of another; and
connecting the internal electrode layers to external contacts, wherein the chemically active ceramic powder comprises (Zr, Ti)O 2 and does not chemically react with a metal component of the metal paste, and wherein Pb is bonded as a result of a chemical reaction between the (Zr, Ti)O 2 and at least one component of surroundings of the Pb.
2. The method of claim 1 , wherein the at least one component of the surroundings of the Pb comprises oxygen, at least one component of the ceramic mass, and a binder or solvent that is contained in the metal paste or the ceramic mass.
3. The method of claim 1 , wherein as a result of a chemical reaction between the chemically active additive and an environment, oxygen is released and/or Pb and/or Cu are bonded.
4. The method of claim 1 , wherein the metal paste contains a non-precious metal.
5. The method of claim 4 , wherein the metal paste contains Cu or Ni.
