  • Colloidal sols of antimony pentoxide in an aqueous medium and their preparation
    Patent number: 5008036
    Abstract: A colloidal dispersion of hydrous antimony pentoxide particles is made by a process which comprises introducing a particulate antimony component selected from the group consisting of antimony metal and antimony trioxide into an essentially aqueous medium and contacting said antimony component with hydrogen peroxide at a temperature of from about 0.degree. C. to about the decomposition temperature of the reaction mixture for a length of time sufficient to convert at least a portion of the antimony component to colloidal particles of hydrous antimony pentoxide.
    Type: Grant
    Filed: August 18, 1975
    Date of Patent: April 16, 1991
    Assignee: Laurel Industries, Inc.
    Inventors: Charles E. Crompton, Abdulla M. Z. Kazi, Inderjit S. Soni
  • Process for making colloidal sols of antimony pentoxide in an aqueous medium
    Patent number: 4348301
    Abstract: A colloidal dispersion of hydrous antimony pentoxide particles is made by a process which comprises introducing a particulate antimony component selected from the group consisting of antimony metal, oxidizable antimony oxides and mixtures thereof into an essentially aqueous medium and contacting said antimony component with hydrogen peroxide at a temperature of from about 0.degree. C. to about the decomposition temperature of the reaction mixture for a length of time sufficient to convert at least a portion of the antimony component to colloidal particles of hydrous antimony pentoxide.
