Abstract:
(EN) These composite particles (1) in which titanium dioxide microparticles are dispersed are provided with silica particles (10) and titanium dioxide microparticles (20). The titanium dioxide microparticles (20) are dispersed within the silica particles (10). The titanium dioxide microparticles (20) are rutile-type microparticles having an average primary particle diameter of 2-8 nm. These composite particles (1) in which titanium dioxide microparticles have high transparency with respect to visible light.
(FR) L'invention concerne des particules composites (1) dans lesquelles des microparticules de dioxyde de titane sont dispersées, présentant des particules de silice (10) et des microparticules de dioxyde de titane (20). Les microparticules de dioxyde de titane (20) sont dispersées à l'intérieur des particules de silice (10). Les microparticules de dioxyde de titane (20) sont des microparticules de type rutile présentant un diamètre moyen de particule primaire compris entre 2 et 8 nm. Ces particules composites (1) comprenant des microparticules dioxyde de titane présentent une transparence élevée en lumière visible.
(JA) 本発明の二酸化チタン微粒子分散複合粒子(1)は、シリカ粒子(10)と、二酸化チタン微粒子(20)とを備える。二酸化チタン微粒子(20)は、シリカ粒子(10)の内部に分散されている。二酸化チタン微粒子(20)は、2nm~8nmの平均一次粒子径を有するルチル型である。本発明の二酸化チタン微粒子分散複合粒子(1)は、可視光に対して高い透明性を有する。
