Method for producing a multilayer component
View Patent ↗A method for producing a multilayer component is described. A stack of green foils, to which inner electrodes including palladium oxide are applied, is sintered. The sintered stack is provided with a silver paste on two or more sides for outer electrodes that are burned into the sintered stack in a further temperature step.
1. A method for producing a multilayer component, the method comprising:
applying palladium oxide to a stack of green foils having inner electrodes, the palladium oxide being applied by a paste having a solids content between 30% and 80%, the solids content comprising palladium oxide;
sintering the stack,
providing the sintered stack with a silver paste on two or more sides for outer electrodes, and
burning the silver paste into the sintered stack in a further temperature step.
2. The method according to claim 1 , wherein palladium oxide is converted to palladium during the sintering process.
3. The method according to claim 1 , wherein the silver paste comprises a glass content.
4. The method according to claim 1 , wherein the silver paste comprises a polymer content.
5. The method according to claim 1 , wherein silver diffuses out of the outer electrodes into the inner electrodes during the burning-in of the silver paste.
6. The method according to claim 1 , wherein palladium diffuses out of the inner electrodes into the outer electrodes during the burning-in of the silver paste.
7. The method according to claim 1 , wherein the inner electrodes of the multilayer component comprise a palladium content of 20% by weight after sintering.
8. The method according to claim 1 , wherein the paste comprises 100% palladium oxide.
9. The method according to claim 1 , wherein the sintering is performed at a temperature greater than about 800° C.
10. The method according to claim 1 , wherein the solids content comprises 100% palladium oxide.
11. The method according to claim 1 , wherein the solids content comprises less than 100% palladium oxide.
12. A method for producing a multilayer component, the method comprising:
providing a stack of green foils having inner electrodes comprising palladium oxide applied thereto,
sintering the stack,
providing the sintered stack with a silver paste on two or more sides for outer electrodes, and
burning the silver paste into the sintered green stack in a further temperature step,
wherein providing the stack of green foils comprises providing green foils with palladium oxide applied by means of a paste, and
wherein the paste has a solids content of between 30% and 80%.
13. The method according to claim 12 , wherein the solids content comprises 100% palladium oxide.
14. The method according to claim 12 , wherein the solids content comprises less than 100% palladium oxide.
15. The method according to claim 12 , wherein palladium oxide is converted to palladium during the sintering process.
16. The method according to claim 12 , wherein the silver paste comprises a glass content.
17. The method according to claim 12 , wherein the silver paste comprises a polymer content.
18. The method according to claim 12 , wherein silver diffuses out of the outer electrodes into the inner electrodes during the burning of the silver paste.
19. The method according to claim 12 , wherein palladium diffuses out of the inner electrodes into the outer electrodes during the burning of the silver paste.
20. The method according to claim 12 , wherein the inner electrodes of the multilayer component comprise a palladium content of 20% by weight after sintering.
