Title
(EN) COLLOIDAL SOL AND METHOD OF MAKING SAME
(FR) SOLUTION COLLOÏDALE ET SON PROCÉDÉ DE FABRICATION
Abstract
(EN)
A colloidal sol and a method of making colloidal sol that is capable of controlling the resulting particle size and more specifically, using a potassium hydroxide process to obtain a colloidal sol having a single peak of average particle sizes.
(FR)
L'invention concerne une solution colloïdale et un procédé permettant de fabriquer une solution colloïdale, ledit procédé permettant de contrôler la taille des particules résultantes. L'invention concerne plus précisément l'utilisation d'un procédé avec hydroxyde de potassium pour obtenir une solution colloïdale dont la taille particulaire moyenne ne présente qu'un seul pic.
