ABSTRACT:
The invention relates to a process for producing diantimony pentoxide having a high oxidation purity.A process for producing an aqueous sol of diantimony pentoxide, which comprises mixing diantimony trioxide (Sb2O3) and an aqueous hydrogen peroxide solution in an aqueous medium, and after the temperature has reached from 50 to 80° C., reacting the diantimony trioxide with the aqueous hydrogen peroxide solution while keeping the reaction temperature at a level not higher by at least 10° C. than a desired set temperature in the temperature range, to thereby obtain a sol having dispersed in the aqueous medium diantimony pentoxide particles which have a primary particle size of from 2 to 50 nm and which have a diantimony trioxide/diantimony pentoxide weight ratio of not higher than 5 wt %.
