Abstract:
A chemical vapor deposition process for applying an antimony doped tin oxide to a surface on a hot glass substrate, comprising:a) providing a hot glass substrate including a surface upon which an antimony doped tin oxide coating is to be deposited; b) providing a uniform, vaporized reactant mixture containing a tin compound, oxygen, water and an organoaritimony compound having at least one Sbâ€”C bond and which will not undergo premature hydrolysis or oxidation at temperatures below 550Â° F., wherein said organoantimony compound is a compound of the form (R1)xSb (R2)3âˆ’x where R1 is an aryl group, R2 is an alkyl group and x=3 or 2; c) delivering the vaporized reactant mixture to the surface of the hot glass substrate, wherein the uniform vaporized reactant mixture reacts to deposit a coating of antimony doped tin oxide on said surface of said hot glass substrate; and d) cooling the coated glass substrate to ambient temperature.
