  • Patent number: 4713338
    Abstract: Porous glass beads for filtation applications having a homogeneous metaloxane structure and comprising oxides of Si, Zr and optionally Ti and Al. A preferred method for making these beads comprises the steps of (a) providing a mother solution of Si and Zr alkoxides in a water soluble solvent, for instance a lower aliphatic alcohol, (b) providing a liquid dispersant phase in which solution (a) is dispersible and stirring this liquid phase sufficiently to cause (a) to be formed into droplets of substantially uniform size when added to (b), (c) adding (a) to (b) at a rate sufficient to provide said droplets and effecting the hydrolysis of the alkoxides contained therein with consecutive gelation of said droplets into corresponding hardened beads of condensed mixed Si and Zr hydroxides, and (d) separating said beads from the liquid phase and drying to achieve the desired porous mixed oxide structure for the beads.

  • Patent number: 4495297
    Abstract: A partly hydrolyzed gelled polysiloxane mass is contacted with a solution of dopant metal compounds which diffuse therein under thermally controlled condition; alternatively, a partly hydrolyzed gelled polysiloxane mass containing distributed therein dopant metal compounds is contacted with a solvent into which said dopant metal compounds will partly diffuse under thermally controlled conditions.
