Abstract
A stable aqueous alkaline metal oxide/silica sol is obtained by adding a water-soluble amine to an acidic metal oxide/silica sol which contains from 5-40% by weight SiO.sub.2, from 1-10.5% by weight of metal oxide, and a water-soluble anionic stabilizing compound selected from the group consisting of water-soluble anionic surfactants having an HLB greater than 8 and water-soluble carboxylic acid polymers with the ratio of metal oxide to water-soluble anionic stabilizing compound being within the range of 0.3:1 to 15:1.
