SURFACE-TREATED SILVER POWDER AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2018/080090

A1

According to the present invention, in a process for producing a silver powder, the content of a surface treatment agent coated on silver powder can be controlled by adjusting the content of a base or acid, which is a second surface treatment agent in a surface treatment step, to adjust the form of a surface treatment agent, present in an aqueous solution functioning as a dispersion medium, to be in the form of a salt, a partial salt (semi-salt), and an emulsion, and variable physical properties of a conductive paste including the produced silver powder can be controlled more simply and in a greater variety of ways without an additional surface treatment process. By adjusting the content of the second surface treatment agent, a conductive paste having a high yield value and storage modulus can be obtained. Therefore, an electrode pattern that is advantageous for forming a fine pattern and has a high aspect ratio can be formed.
