[0300] [surface treatment]

[0301] The supernatant was removed from the metal powder slurry obtained by the above wet method without drying the metal powder, and the prepared coupling agent aqueous solution and metal powder were mixed for 60 minutes by any of the following methods. With respect to 50mL of coupling agent aqueous solution, the mass of metal powder for surface treatment is 20g respectively.

[0302] (1) Rotating paddle (300rpm) + ultrasonic wave (manufactured by Techjam Co., Ltd., ultrasonic cleaner 3 frequency type / W-113) (power 100W, frequency 100kHz);

Abstract

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 recovered 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.

Description

technical field [0001] The present invention relates to a metal powder paste which is suitable for the production of electrodes for chip laminated ceramic capacitors and has excellent sintering retardation, and a production method thereof. Background technique [0002] Chip laminated ceramic capacitors form a structure in which ceramic dielectrics and internal electrodes are stacked in layers to form an integrated structure. The laminated layers constitute capacitor elements respectively, and these elements are connected through external electrodes to form an electrical parallel connection, thus forming a whole. Small and high-capacity capacitors. [0003] In the manufacture of chip laminated ceramic capacitors, thin sheets of dielectric are manufactured as follows. That is, first, to BaTiO 3 Adding a dispersant or an organic binder and a solvent as a molding aid to the dielectric raw material powder, and going through the steps of pulverization, mixing and defoaming to ob...
