ABSTRACT:
A continuous, chemical vapor deposition method for producing a coated glass article is disclosed. A glass substrate is advanced continuously, while hot, past first and second treating stations. A non-oxidizing atmosphere is maintained in the vicinity of the first treating station, while an oxidizing atmosphere is maintained in the vicinity of the second station. A non-oxidizing gas which contains a silane, e.g., SiH.sub.4, is directed from the first treating station against a surface of the glass to form a silicon coating on that surface. An oxidizing gas which includes a metal compound in the vapor phase is directed from the second station against the silicon-coated surface of the article. The process is controlled so that the silane-containing gas forms a reflective silicon coating on the glass surface, the oxidizing gas which includes a metal compound forms a coating of an oxide of the metal, and oxidation before the article reaches the second treating station forms a silicon oxide layer on the silicon which is of sufficient thickness that the metal oxide layer is substantially free of pinholing.
