  • Patent number: 8003707
    Abstract: A modified sol-gel method to create metal-rich siliceous material, such as colloidal silica or aluminosilicate particles is disclosed. Initially, the metal salt of choice is added to a silicic acid solution or a silicic acid solution containing aluminum salt. The aluminum is added to vary the metal-support interaction as it forms Al—O—Si linkages within the silica matrix. Besides aluminum, other metals can be added that form M—O—Si (M=Ti, B, etc.) linkages, which do not become reduced when treated with a reducing agent. Once the metal, silicic acid and/or aluminum salt is generated, it is subjected to colloidal growth by addition to a basic heel. Upon colloidal synthesis, the metal salt containing colloidal particle is left as is to maximize colloidal stability or is reduced with hydrazine to produce the zero valence metal-containing colloidal particle.

  • Patent number: 7922938
    Abstract: A process for producing a fine silver particle colloidal dispersion the fine silver particles of which have a larger average particle diameter than those in the conventional Carey-Lea process and also which has superior dispersion stability. An aqueous silver nitrate solution is allowed to react with a mixed solution of an aqueous iron(II) sulfate solution and an aqueous sodium citrate solution, and the resultant reaction fluid containing an agglomerate of fine silver particles is left at 0 to 100° C. to obtain an agglomerate of fine silver particles having grown into granular particles. Next, this agglomerate of fine silver particles having grown into granular particles is filtered, and, to the resultant cake of the agglomerate of fine silver particles, pure water is added to obtain a fine silver particle colloidal dispersion having an average particle diameter of 20 to 200 nm.
