Title
(EN) HEAT-RESISTANT TRANSPARENT COATED GLASS ARTICLE
(FR) ARTICLE EN VERRE TRANSPARENT POSSEDANT UN REVETEMENT ET RESISTANT A LA CHALEUR
Abstract
(EN)
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 Å and preferably in the range of about 7 Å to 20 Å. 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.
(FR)
Article en verre transparent résistant à la chaleur comportant des couches superposées déposées sur un substrat en verre et comprenant une ou plusieurs couches (20) réfléchissant les infrarouges, dont chacune porte, sur sa surface tournant le dos au substrat, une couche barrière (18, 22) en métal niobium possédant une épaisseur de 25 Å maximum et, de préférence, se situant dans une plage de 7 Å à 20 Å. L'autre surface, tournée vers le substrat, de chaque couche (20) réfléchissant les infrarouges peut comporter une couche barrière (18, 22) en métal niobium ou, de préférence, en oxyde de métal. On peut utiliser des couches (16, 24) en nitrure de métal, tel que du nitrure de silicium, entre les couches (20) réfléchissant les infrarouges situées à proximité les unes des autres, ainsi qu'en tant que couche extérieure de protection.
