Summary:Stable aqueous silica dispersions are produced by adding effective amounts of certain primary, secondary, and tertiary amino alcohols as defined herein. Such dispersions remain non-dilatant, even under high stress. L'invention concerne des dispersions de silice stables aqueuses, que l'on peut produire en ajouter des quantités efficaces de certains amino-alcools primaires, secondaires, et tertiaires tels que définis dans cette invention. Ces dispersions se ne dilatent pas, même lorsqu'elles sont soumises à une contrainte élevée.
