Abstract
Method for forming conductive, transparent coating such as may be used on the interior surface of a vitreous tubular member. In a carrier gas and exterior to the member to be coated, there is formed a vapor from a material substantially comprising organic tin halide compound having a predetermined condensation temperature and a predetermined decomposition temperature, with the temperature of the carrier gas and the formed vapor maintained between these temperatures. The member to be coated is heated to a temperature greater than the decomposition temperature of the organic tin halide compound and the heated carrier gas and formed vapor are longitudinally flowed through the heated tubular member. Upon contact with the heated tubular member, the vapor breaks down to form the transparent conducting coating. The carrier gas and residual heated vapor are flowed out of the member being coated and are cooled to condense and collect the residual material. There are also provided very high performance fluorine-doped tin oxide coatings.
