Abstract:
(EN) The objective of the present invention is to provide a method for producing vanadium dioxide-containing particles that have a narrow thermal hysteresis width of the phase transition and a small average primary particle diameter. A method for producing vanadium dioxide-containing particles according to the present invention produces vanadium dioxide-containing particles that are doped with a different metal element and have an average primary particle diameter of 30 nm or less and a thermal hysteresis width of the phase transition of less than 25°C. This method for producing vanadium dioxide-containing particles is characterized by comprising a step wherein a vanadium-containing compound and a different metal element-containing compound are supplied to a flow reactor 1 and are subjected to hydrothermal synthesis therein.
(FR) L'objectif de la présente invention est de fournir un procédé de production de particules contenant du dioxyde de vanadium qui ont une largeur d'hystérésis thermique étroite de la transition de phase et un petit diamètre moyen de particule primaire. Un procédé de production de particules contenant du dioxyde de vanadium selon la présente invention produit des particules contenant du dioxyde de vanadium qui sont dopées avec un élément métallique différent et ont un diamètre moyen de particule primaire de 30 nm ou moins et une largeur d'hystérésis thermique de la transition de phase de moins de 25 °C. Ce procédé de production de particules contenant du dioxyde de vanadium est caractérisé en ce qu'il comprend une étape dans laquelle un composé contenant du vanadium et un composé contenant un élément métallique différent sont introduits dans un réacteur d'écoulement 1 et sont soumis à une synthèse hydrothermique dans celui-ci.
(JA) 本発明の課題は、相転移の熱ヒステリシス幅が小さく、かつ、平均一次粒径の小さい二酸化バナジウム含有粒子の製造方法を提供することである。当該二酸化バナジウム含有粒子の製造方法は、異種金属元素がドープされ、平均一次粒径が30nm以下かつ相転移の熱ヒステリシス幅が25℃未満の二酸化バナジウム含有粒子を製造する二酸化バナジウム含有粒子の製造方法であって、流通式反応装置1にバナジウム含有化合物及び異種金属元素含有化合物を供給して水熱合成する工程を有することを特徴とする。
