Abstract

An electrical component includes a base. The base is made of a sintered ceramic, and at least one electrode that is inside the sintered ceramic. The at least one electrode has a surface that contains metal. The surface is adjacent to the sintered ceramic. In the component, a redox potential of the metal is less than or equal to a redox potential of copper.

Claims (15)

1. A method for producing an electrical component, comprising:

sintering a base comprising a ceramic and at least one internal electrode that contains a first metal, where sintering occurs in a sintering chamber, the sintering chamber containing a gas and a sintering aid, the sintering aid comprising a second metal having a redox potential that is at least as great as a redox potential of the first metal.

2. A method for producing an electrical component, comprising:

sintering a base comprising a ceramic and at least one internal electrode that contains a first metal, where sintering occurs in a sintering chamber, the sintering chamber containing a gas and a sintering aid, the sintering aid binding to, and releasing, the gas, the sintering aid comprising a second metal having a redox potential that is at least as great as a redox potential of the first metal.

3. The method of claim 1 , wherein the first metal comprises copper and the second metal comprises copper.

4. The method of claim 1 , wherein the gas comprises oxygen.

5. The method of claim 1 , wherein the gas comprises hydrogen and water vapor.

6. The method of claim 1 , wherein, following sintering, the ceramic exhibits a piezoelectric effect.

7. The method of claim 1 , wherein the ceramic comprises lead-zirconate-titanate.

8. The method of claim 2 , wherein the first metal comprises copper.

9. The method of claim 2 , wherein the gas comprises oxygen.

10. The method of claim 2 , wherein the gas comprises hydrogen and water vapor.

11. The method of claim 2 , wherein, following sintering, the ceramic exhibits a piezoelectric effect.

12. The method of claim 2 , wherein the ceramic comprises lead-zirconate-titanate.

13. The method of claim 2 , wherein the second metal comprises copper.
