Abstract: front page image
(EN)Disclosed is an extremely stable liquid dispersion of fine core/shell complex oxide particles, wherein the surface negative charge and the core covering ratio by the shell are high. The fine core/shell complex oxide particles are obtained by covering the surfaces of core particles, namely the surfaces of fine oxide particles or fine complex oxide particles that do not contain silicon and/or aluminum as a main component, with shells that are composed of a complex oxide which contains silicon and aluminum as main components. The weight ratio of the silicon content to the aluminum content in the shells in terms of oxides, namely SiO2/Al2O3 is within the range of 2.0-30.0.
(FR)L'invention porte sur une dispersion liquide extrêmement stable de fines particules d'oxyde complexe cœur-écorce, dans laquelle la charge négative de surface et le rapport de recouvrement du cœur par l'écorce sont élevés. Les fines particules d'oxyde complexe cœur-écorce sont obtenues par recouvrement des surfaces de particules de cœur, à savoir les surfaces de fines particules d'oxyde ou de fines particules d'oxyde complexe qui ne contiennent pas de silicium et/ou d'aluminium comme composant principal, par des écorces qui sont composées d'un oxyde complexe qui contient du silicium et de l'aluminium comme composants principaux. Le rapport en poids de la teneur en silicium à la teneur en aluminium dans les écorces en termes d'oxyde, à savoir SiO2/Al2O3 se situe dans la plage de 2,0-30,0.
(JA) ケイ素および/またはアルミニウムを主成分として含まない酸化物微粒子または複合酸化物微粒子をコア粒子として、その表面をケイ素とアルミニウムとを主成分として含む複合酸化物からなるシェルで被覆したコアシェル型複合酸化物微粒子の、シェルに含まれるケイ素とアルミニウムの含有量が酸化物換算基準の重量比でSiO2/Al23=2.0~30.0の範囲にあることによって、表面負電荷量およびコアに対するシェルの被覆率が高く、超安定なコアシェル型複合酸化物微粒子の分散液が得られる。
