Method for forming tin oxide coating on glass

Fluorine doped tin oxide coatings on glass are prepared by providing a uniform, vaporized reactant mixture containing an organotin compound, HF, water and oxygen, and delivering the reactant mixture to the surface of the hot ribbon of glass, where the compounds react to form the fluorine doped tin oxide coating. The fluorine doped tin oxide coatings applied in accordance with the invention exhibit lower sheet resistance, and improved uniformity in sheet resistance over the coated surface of the glass.
