  • SILICA-COATED METAL OXIDE SOLS HAVING VARIABLE METAL OXIDE TO SILICA RATIO
    Publication number: 20080085412
    Abstract: This invention provides metal-rich siliceous compositions and methods of preparing such compositions. The compositions have comprehensibly variable and controllable metal oxide to silica ratios, surface morphology, porosity, and surface area. The method includes preparing a silicic acid, a metal oxide dispersion, and a basic heel solution. The silicic acid and metal oxide dispersion are mixed to create a blend and the blend is controllably added to the basic heel solution to form a siliceous material including colloidal silica-coated metal oxide particles.
