Sols of Sb2O3, SnO2, TiO2 and ZrO2 in organic polar liquids are prepared by reacting a soluble salt of the metal with water and ammonia in a solution of the liquid. The reaction produces the metal oxide in colloidal dispersion and an insoluble ammonium salt, which precipitates and is filtered off. Sols in liquids which are solvents for organic polymers are used to incorporate metal oxides into the polymers to provide flame resistance and other desirable properties.
