Title (EN) DISPERSION COMPRISING CERIUM OXIDE AND SHEET SILICATE
(FR) DISPERSION COMPRENANT DE L'OXYDE DE CÉRIUM ET DU PHYLLOSILICATE
Abstract: front page image
(EN)A dispersion comprising cerium oxide particles and particles of one or more sheet silicates, where the zeta potential of the sheet silicate particles is negative and that of the cerium oxide particles is positive or equal to zero, and the zeta potential of the dispersion is negative overall, the mean particle diameter of the cerium oxide particles and the mean particle diameter of the sheet silicate particles is not more than 100 nm and the pH of the dispersion is from 7.5 to 10.5, preferably from 9 to 10.
(FR)L'invention concerne une dispersion qui comprend des particules d'oxyde de cérium et des particules d'un ou de plusieurs phyllosilicates, dans laquelle le potentiel zêta des particules de phyllosilicate est négatif et celui des particules d'oxyde de cérium est positif ou égal à zéro, et le potentiel zêta de la dispersion est globalement négatif. Le diamètre particulaire moyen des particules d'oxyde de cérium et le diamètre particulaire moyen des particules de phyllosilicate n'est pas supérieur à 100 nm et le pH de la dispersion est compris entre 7,5 et 10,5; de préférence entre 9 et 10.
