METAL POWDER PASTE AND METHOD FOR PRODUCING SAME

摘要

A method for producing a surface-treated metal powder, which comprises: a step for preparing a metal powder dispersion liquid by mixing a metal powder with an aqueous solution of a coupling agent having an amino group; a step for recovering, as a residue, the metal powder from the metal powder dispersion liquid; and a step for cleaning the metal powder, which has been re-covered as a residue, with use of an aqueous solvent. This method for producing a surface-treated metal powder provides a method for producing a surface-treated copper powder or metal powder which has excellent sintering delaying properties and is suitable for use in the production of an electrode for multilayer ceramic chip capacitors.

1. A method for producing a metal powder paste comprising a step of preparing the paste by dispersing in a solvent a surface-treated metal powder including 100 to 1000 μg of one or more of Si, Ti, Al, Zr, Ce and Sn in relation to 1 g of the metal powder and having a weight percentage of N of 0.02% or more in relation to the metal powder, and a carboxyl group- or amino group-containing organic compound.
