ABSTRACT In a method for forming metal oxide films by contacting a hot surface with a coating composition comprising an organometallic coating reactant which thermally decomposes to a metal oxide, the improvement which comprises adding to the coating composition a relatively nontoxic organic compound having a boiling point of at least 200°C and a high surface tension. The organic compound modifies the rate of film formation and decreases the particle size of the metal oxide. The particle lifetime is increased in the coating composition in the hot coating environment. This increases the concentration of metal- containing coating reactant at the surface of the substrate to be coated resulting in the deposition of a more uniform, less porous, and therefore more durable, metal oxide film.
