Process for making colloidal sols of antimony pentoxide in an aqueous medium

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, 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 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.
