Combustion deposition of metal oxide coatings deposited via infrared burners

A method of applying a coating to a substrate using combustion deposition, the method comprising:

• providing a substrate having at least one surface to be coated;
• selecting a reagent, the reagent being selected such that at least a portion of the reagent forms the coating;
• introducing a precursor to be combusted with the reagent, the precursor including silicon;
• combusting, using at least one infrared burner, at least a portion of the reagent and the precursor to form a combusted material;
• and
• providing the substrate in an area so that the substrate is heated sufficiently to allow the combusted material to form the coating, directly or indirectly, on the substrate,
• wherein the deposited coating comprises silicon oxide, and
• wherein the coating is substantially uniform and increases visible transmission of the glass substrate by at least about 1.7%.

A method of forming a coating on a glass substrate using combustion deposition, the method comprising:

• providing a glass substrate having at least one surface to be coated;
• selecting a reagent, the reagent being selected such that at least a portion of the reagent is used in forming the coating;
• introducing a precursor to be combusted with the reagent;
• combusting, via IR radiation from an IR radiation source, the IR radiation having a wavelength of about 2.5-3.5 microns distributed substantially two-dimensionally, at least a portion of the reagent and the precursor to form a combusted material, the combusted material comprising non-vaporized material;
• and
• providing the glass substrate in an area about 2-5 mm from the IR radiation source so that the glass substrate is heated sufficiently to allow the combusted material to form the coating substantially uniformly, directly or indirectly, on the glass substrate,
• wherein the coating is substantially uniform.
