Title (EN) METHOD FOR MANUFACTURING METAL POWDER
(FR) PROCÉDÉ DE FABRICATION D'UNE POUDRE MÉTALLIQUE
(JA) 金属粉末の製造方法
Abstract:
(EN) Through the present invention, metal particles can be uniformly coated with an oxide, and oxide aggregates are prevented from forming. The method for manufacturing a metal powder according to the present invention comprises mixing a dispersion including a metal powder and a metal complex having a ligand, and water including acid or alkali, and thereby coating at least a portion of the surface of the metal powder with an oxide generated from the metal complex.
(FR) La présente invention permet un revêtement uniforme de particules métalliques avec un oxyde, et empêche la formation d'agrégats d'oxyde. Selon la présente invention, le procédé de fabrication d'une poudre métallique consiste à mélanger une dispersion comprenant une poudre métallique et un complexe métallique possédant un ligand, et de l'eau comprenant un acide ou un alcali, et ainsi à revêtir au moins une partie de la surface de la poudre métallique avec un oxyde généré à partir du complexe métallique.
(JA) 金属粒子に酸化物を均一に被覆することができ、酸化物の凝集体が形成されることを防止する。金属粉末の製造方法は、金属粉末、および配位子を有する金属錯体を含む分散液と、酸またはアルカリを含む水とを混合することで、前記金属錯体から生成される酸化物によって前記金属粉末の表面の少なくとも一部を被覆する。
