Stable metal oxide sols comprising an anhydrous alcohol having metal oxide particles colloidally dispersed therein is disclosed. This sol composition is formed by the hydrolysis of a metal alkoxide to form metal oxide particles, removal of the particles from the resulting mother liquor from such a reaction, and the redispersing of the metal oxide powders in an anhydrous alcohol solvent.
