PURPOSE: A heat-resistant transparent glass article is provided to produce the glass substrates having coatings that are capable of withstanding high temperatures such as those encountered during glass tempering and bending, and those encountered during the cleaning cycle of self cleaning ovens. CONSTITUTION: A heat-resistant transparent glass article is formed with a film stack deposited on a glass substrate, the film stack comprising one or more infrared reflective films(20) each bearing on its surface facing away from the substrate a barrier film of niobium metal(18,22) having a thickness of up to 25 angstrom and preferably in the range of about 7 to 20 angstrom. A barrier film of niobium metal(18,22) or, preferably, a metal oxide may be formed on the other surface(facing the substrate) of each infrared reflective film(20). Metal nitride films(16,24) such as silicon nitride may be employed between neighboring infrared reflective films(20), and as an outer protective film. |
