(JA) オキシ水酸化鉄ナノ分散液
Abstract: front page image
(EN) The purpose of the present invention is to provide an iron oxyhydroxide nanodispersion liquid that is stable and does not contain any components derived from an auxiliary component. The iron oxyhydroxide nanodispersion liquid according to the present invention is obtained by dispersing, in a solvent, particles of which the main component is an iron oxyhydroxide and, in terms of the average particle diameter, d50 is not larger than 0.2 μm and d90 is not larger than 1 μm. The iron oxyhydroxide is preferably β-iron oxyhydroxide, and preferably does not contain a component other than a solvent, a pH adjuster, and substances derived from an iron compound and/or a base.
(FR) La présente invention a pour objet une nanodispersion liquide d’oxyhydroxyde de fer qui est stable et qui ne contient pas de quelconques constituants issus d’un constituant auxiliaire. La nanodispersion liquide d’oxyhydroxyde de fer selon la présente invention est obtenue par dispersion, dans un solvant, de particules dont le constituant principal est un oxyhydroxyde de fer et, en ce qui concerne le diamètre moyen des particules, d50 est inférieur ou égal à 0,2 µm et d90 est inférieur ou égal à 1 µm. L’oxyhydroxyde de fer est de préférence de l’oxyhydroxyde de fer β et de préférence ne contient pas un constituant autre qu’un solvant, un agent de réglage du pH et des substances issues d’un composé du fer et/ou d’une base.
(JA) 安定で、補助成分に由来する成分を含有しないオキシ水酸化鉄のナノ分散液を提供することを目的とする。 本発明のオキシ水酸化鉄のナノ分散液は、オキシ水酸化鉄を主成分とした、平均粒径d50が0.2μm以下で、d90が1μm以下である粒子が溶媒に分散してなるナノ分散液である。オキシ水酸化鉄は、β-オキシ水酸化鉄であるのが好ましい。また、鉄化合物及び塩基の少なくともいずれかに由来する物質、pH調整剤、及び溶媒以外の成分を含有しないものが好ましい。
