METHOD OF MAKING COLLOIDAL DISPERSION OF PARTICLES OF ANTIMONY TETRAOXIDE HYDRATE ANTIMONYY PENTAOXIDE OR MIXTURE THEREOF

摘要

Process for preparing a colloidal dispersion of hydrated antimony oxide particles, in particular hydrated antimony tetroxide, hydrated antimony pentoxide or mixtures thereof, directly from particles of antimony trioxide of a size greater than about 4,000 å, characterized in that it comprises heating, at a temperature of about 90 to 105º c, and for a sufficient time to form said colloidal dispersion, a dispersion of said antimony trioxide in an aqueous solution of hydrogen peroxide, said dispersion containing less than 0.002% of ionizable impurities.
