Abstract
Processes for coating substrates, in particular substrates including shielded surfaces, with tin oxide-containing coatings are disclosed. Such processes comprise contacting a substrate with a tin oxide precursor, preferably maintaining the precursor coated substrate at conditions to equilibrate the coating, and then oxidizing the precursor to form a substrate containing tin oxide. Also disclosed are substrates coated with tin oxide-containing coatings.

A process for coating an inorganic three dimensional substrate with doped tin oxide comprising:
- contacting an inorganic three dimensional substrate which includes external surfaces and shielded surfaces which are at least partially shielded by other portions of said substrate with a composition comprising a tin chloride-forming compound at conditions effective to form a tin chloride-forming compound containing coating on at least a portion of said substrate;
- forming a liquidus tin chloride forming compound containing coating on at least a portion of the three dimensions of said substrate including the shielded surface of said substrate,
- contacting said substrate with at least one fluorine component at conditions effective to form a fluorine component-containing coating on at least a portion of said substrate including at least a portion of the three dimensions of said substrate including the shielded surfaces of said substrate;
- and
- contacting said substrate having said tin chloride-forming compound containing coating and said fluorine component-containing coating thereon with an oxidizing agent at conditions effective to convert tin chloride forming compound to tin oxide and form a fluorine doped tin oxide coating on at least a portion of said three dimensions of said substrate including the shielded surfaces of said substrate.
A process for coating an inorganic three dimensional substrate with tin oxide comprising:
- contacting an inorganic three dimensional substrate which includes external surfaces and shielded surfaces which are at least partially shielded by other portions of said substrate with a composition comprising a tin chloride-forming compound at conditions effective to form a tin chloride-forming compound containing coating on at least a portion of said substrate;
- forming a liquidus tin chloride-forming compound containing coating on at least a portion of the three dimensions of said substrate including the shielded surfaces of said substrate and at conditions effective to do at least one of the following:
- (1) coat a larger portion of said substrate with said tin chloride-forming compound;
- (2) distribute said tin chloride-forming compound over said substrate;
- and (3) make said tin chloride-forming compound containing coating more uniform in thickness;
- and
- contacting said substrate with said tin chloride-forming compound containing coating with an oxidizing agent at conditions effective to convert the tin chloride forming compound to tin oxide and form a tin oxide coating on at least a portion of said three dimensions of said substrate including the shielded surfaces of said substrate.
A process for coating surfaces of an inorganic three dimensional substrate with tin oxide which comprises:
- contacting an inorganic three dimensional substrate with a composition comprising a tin oxide precursor powder at conditions effective to form a coating containing tin oxide precursor on at least a portion of the substrate;
- forming a liquidus tin oxide precursor on at least a portion of the three dimensions of said substrate including the shielded surfaces of said substrate and at conditions effective to do at least one of the following:
- (1) coat a larger portion of said substrate with said coating containing tin oxide precursor;
- (2) distribute said coating containing tin oxide precursor over said substrate;
- and (3) make said coating containing in oxide precursor more uniform in thickness;
- and contacting said coated substrate with an oxidizing agent at conditions effective to convert said tin oxide precursor to tin oxide on at least a portion of said three dimensions of said substrate and form a substrate having a tin oxide-containing coating.
