Abstract
There is disclosed a process for preparing stable colloidal sols of antimony pentoxide in organic solvents which comprises the steps of adjusting an amount of an organic base in an aqueous colloidal solution of antimony pentoxide to, in terms of % by weight, 2 to 30% based on antimony pentoxide in the aqueous colloidal solution of antimony pentoxide; adding an organic acid in an amount of 0.2 to 20%; and replacing a dispersing medium of the colloidal solution from water to an organic solvent.
