Colloidal sols of antimony pentoxide in an aqueous medium and their preparation

摘要

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 DEG 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.
