金属微粒子の製造方法
Document Type and Number:
Japanese Patent JP5875437
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing metal fine particle which can stably prepare metal fine particles and, when burning dispersion liquid of metal fine particles, can burn the particles at a burning temperature of 150°C or less.SOLUTION: A method for producing metal fine particle includes: a first process of preparing metal fine particles, the surface of which is covered with a 6-18C first carboxylic acid having a straight chain or branched structure and a 6-18C first amine having a straight chain or branched structure; a second process of mixing the metal fine particles prepared in the first process with a 5-22C second carboxylic acid having a neo-branched structure to substitute the first carboxylic acid with which the surface of the metal fine particles is covered into a second carboxylic acid; and a third process of mixing the metal fine particles, the surface of which is covered with the second carboxylic acid and the first amine, with a second amine as a 4-22C of primary amine having straight chain or branched structure to provide metal fine particles, the surface of which is covered with the second carboxylic acid and the second amine.
