Abstract
The present invention provides a process for producing a diantimony pentoxide sol, characterized in that a diantimony pentoxide sol having a particle size of 5 to 30 nm is used as a nuclear sol and the sol is grown to an arbitrary particle size, preferably a particle size of 40 to 300 nm. The process comprises adding a hydrogen peroxide solution and diantimony trioxide into a sol comprising diantimony pentoxide particles as a raw material, and coating the diantimony pentoxide particles with a resulting antimony compound, preferably diantimony pentoxide. In the process, the coating is preferably carried out in such a manner that a particle size of particles in a sol as a raw material increases by a factor of 1.3 to 60.
