Abstract:
A method of producing a glass substrate having a first layer formed on a surface of the substrate by low-temperature CVD includes (1) a step of preparing the glass substrate and (2) a step of forming the first layer on the glass substrate by the low-temperature CVD, wherein, in the glass substrate after the step (2), an integrated value after a baseline correction in a wavenumber range of 2600 cm -1 to 3800 cm -1 in a peak due to OH groups obtained by an FTIR measurement on the first layer is 9.0 or less, and the C content of the first layer is 1.64 at% or less.
Abstract:
The invention relates to a glazing comprising a transparent glass substrate containing ions of at least one alkali metal, and a transparent layer of silicon oxycarbide (SiO x C y ) having total thickness E with (a) a carbon-rich deep area extending from depth P 3 to depth P 4 , where the C:Si atomic ratio is greater than or equal to 0.5, and (b) a superficial area having a low carbon content, extending from depth P 1 to depth P 2 , where the C:Si atomic ratio is lesser than or equal to 0.4, with P 1 2 3 4 , and (P 2 -P 1 ) + (P 4 -P 3 ) 1 and P 2 representing between 10 and 70% of total thickness E of the silicon oxycarbide layer and the distance between P 3 and P 4 representing between 10 and 70% of total thickness E of the silicon oxycarbide layer.
Abstract:
The invention relates to a method for coating a float glass strip (2) following the production process of the float glass strip, wherein the float glass strip (2) is transported from a float glass bath by a conveying device (3), in which the float glass strip (2) cools and/or is cooled, wherein coating is performed in at least two coating devices (4.1 to 4.n) arranged one after the other along the conveying device (3), wherein coating is performed by each of the coating devices (4.1 to 4.n) at a location at which the temperature of the float glass strip (2) lies within a temperature range that is different from the temperature ranges of the float glass strip (2) in the region of the other coating devices (4.1 to 4.n). The coating is performed preferably by means of flame pyrolysis (combustion CVD) at normal atmospheric pressure.
Abstract:
The subject of the invention is a mirror, especially a front-face mirror and/or a mirror for concentrating solar energy, comprising a material, which mirror comprises a substrate coated with a multilayer comprising at least one silver layer and at least one protective layer located on top of said at least one silver layer, at least one protective layer being characterized in that at least one of its physicochemical characteristics varies with the distance from the substrate.
