Abstract

The invention provides MLCC copper-coated nickel alloy inner electrode slurry. The copper-coated nickel alloy material is used as a main raw material of a copper inner electrode, and comprises according to a specific slurry ratio, 50-65wt% of copper-coated nickel alloy powder; 5-15 wt% of an inorganic ceramic additive; and 21-44wt% of an organic carrier. The copper inner electrode slurry prepared by the method has the characteristics of low resistivity, good weldability and welding resistance, effectively improves the defects of cracking and the like of an internal electrode layer of a nickel inner electrode during sintering, and is novel base metal copper inner electrode slurry which is good in dispersity, uniform in particle size distribution, relatively good in forming process and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of base metal electronic paste, in particular to a MLCC copper-clad nickel alloy internal electrode paste and its application. Background technique [0002] At present, according to market requirements, nickel-electrode multilayer ceramic capacitors (MLCC), as one of the most important electronic components, are also constantly developing in the direction of miniaturization, high capacity, and high reliability. As a result, the number of silk screen layers inside the capacitor has been continuously increased, and the difficulty of production technology has also increased. This requires that the electrode layer of each layer inside the MLCC electrode has good conductivity and the electrode is more continuous after sintering. [0003] However, when metal nickel and ceramic media are co-fired at high temperature in a reducing atmosphere, Ni is easy to combine with BaTiO 3 In Ni-BaTiO 3 A liquid phase alloy f...
