Method of making coated article with color suppression coating including flame pyrolysis deposited layer(s)
View Patent ↗A method of making an oven door, or other coated article, is provided so as to have a color suppression coating on a substrate such as a glass substrate. Flame pyrolysis (or combustion CVD) is used in depositing at least part of a color suppression coating. For example, in an example embodiment of this invention, flame pyrolysis can be used to deposit a single SnO 2 layer from suitable Sn inclusive precursor(s), or alternatively a multi-layer coating may be formed at least partially using flame pyrolysis. In another example embodiment, the coating may include a base layer of silicon oxide formed using flame pyrolysis, and another layer of tin oxide formed in any suitable manner over the base layer of silicon oxide.
1. A method of making an oven door, the method comprising:
providing a glass substrate; and
using flame pyrolysis to deposit a first layer comprising tin oxide on the glass substrate for the oven door, then using flame pyrolysis to deposit a silicon oxide layer over and contacting the first layer comprising tin oxide, and using flame pyrolysis to depositing a second layer comprising tin oxide over and contacting the layer comprising silicon oxide, so that the layer comprising silicon oxide is located between and contacting the first and second layers comprising tin oxide, and
wherein at least one of the first and second layers comprising tin oxide comprises hydrogen and/or carbon.
2. The method of claim 1 , further comprising using flame pyrolysis to deposit another layer comprising tin oxide on another side of the glass substrate so that layers deposited via flame pyrolysis are located on opposite sides of the glass substrate.
3. The method of claim 1 , wherein the oven door has a visible transmission of at least 30%.
4. The method of claim 1 , wherein the oven door has no IR reflecting layer comprising Ag and/or Au.
5. The method of claim 1 , wherein the flame pyrolysis used in depositing the first layer comprising tin oxide introduces at least dimethyl tin and/or tetramethyl tin into a flame in order to cause the layer to be deposited.
