Title (EN) DISPERSION LIQUID OF COMPOSITE PARTICLES, AND METHOD FOR PRODUCING SAME
(FR) LIQUIDE DE DISPERSION DE PARTICULES MÉTALLIQUES ET SON PROCÉDÉ DE PRODUCTION
(JA) 複合粒子の分散液及びその製造方法
Abstract:
(EN) The objective of the present invention is to provide a dispersion liquid of metal particles that is for producing an exhaust-gas purifying catalyst in which the aggregation of catalyst metals during high-temperature endurance is suppressed. The aforementioned objective can be achieved by a dispersion liquid comprising a dispersion medium, an organic base having a molecular weight of from 30 to 500, and composite particles that are dispersed in the dispersion medium and that include a first metal and a second metal, wherein: the first metal is palladium and/or platinum; and the second metal is a metal having a higher melting point than the melting point of the first metal.
(FR) La présente invention concerne un liquide de dispersion de particules métalliques qui est destiné à produire un catalyseur de purification de gaz d'échappement assurant la suppression de l'agrégation des métaux catalytiques à haute température. Ledit liquide de dispersion comprend un milieu de dispersion, une base organique ayant un poids moléculaire de 30 à 500, et des particules composites qui sont dispersées dans le milieu de dispersion et qui comprennent un premier métal et un second métal, ledit premier métal étant du palladium et/ou du platine, et ledit second métal étant un métal présentant un point de fusion supérieur au point de fusion du premier métal.
(JA)  本発明は、高温耐久時における触媒金属の凝集を抑制した排気ガス浄化用触媒を製造するための金属粒子の分散液を提供することを課題とする。上記課題は、分散媒と、分子量が30~500である有機塩基と、前記分散媒に分散されている、第1の金属及び第2の金属を含む複合粒子とを含む分散液であって、第1の金属がパラジウム及び/又は白金であり、第2の金属が第1の金属の融点よりも高い融点を有する金属である、前記分散液によって解決することができる。
