Abstract

The invention discloses a function ceramic component and a method for forming an electrode on a function ceramic layer. The function ceramic component comprises multiple function ceramic layers, wherein at least one function ceramic layer has an electrode. The method for forming the electrode on the function ceramic layer comprises steps that conductive paste is printed on an organic film layer according to an image pattern of a set pattern to form an assembly; the conductive paste is dried; the dried assembly is pressed onto a ceramic substrate or a ceramic body, and the conductive paste is combined with the ceramic substrate or the ceramic body; the pressed assembly is sintered to make the conductive paste form the electrode, and the organic film layer is burned off. The method is advantaged in that the conductive paste after being pressed into the ceramic substrate or the ceramic body can be prevented from penetrating into pores, thereby occurrence of the short circuit can be prevented.

Description

technical field [0001] The invention relates to the technical field of functional ceramics, in particular to a functional ceramic element and a method for forming electrodes on a functional ceramic layer. Background technique [0002] Functional ceramics, especially multilayer piezoelectric ceramic elements, multilayer capacitive elements, multilayer inductive elements, etc., need to print electrodes on both sides of each ceramic layer to provide electrical signals to the ceramic layer. Functional ceramics are generally composed of N layers of ceramics and N+1 layers of electrodes, where N≥1. [0003] However, due to structural design requirements, some ceramic layers or ceramic green layers are relatively thin, for example, the thickness is on the order of microns; When the electrodes are connected, the phenomenon of metal conductor paste penetration will occur, which makes the electrodes on both sides of the ceramic layer conductive, and then makes the ceramic component i...
