  • Metal oxide coated silica shells
    Patent number: 5512094
    Abstract: The present invention discloses a novel high surface area powder composition in which the individual powder particles comprise hollow silica shells, e.g., amorphous hydroxylated silica, coated with finely distributed surface accessible metal oxides. The invention also discloses metallic coatings, which are obtained by converting at least a portion of the oxide coatings into the corresponding metals.
