Abstract

The invention discloses coated glass. The coated glass comprises a glass substrate and a first medium layer which is stacked and bonded to one surface of the glass substrate. The coated glass is characterized in that at least one functional unit is stacked and bonded to the outer surface of the first medium layer, the at least one functional unit is composed of a first antioxidation layer, a first functional layer, a second antioxidation layer and a second medium layer orderly stacked and bonded from a position close to the first medium layer to outside, and the first medium layer and the second medium layer are metal-doped silicon carbide films. Through use of high-refractive index, large-hardness and low-expansion coefficient silicon carbide films as the medium layers, low-radiation glass color shift problems are solved, the product integral performances are improved and the novel coated glass product is obtained. The coated glass can be used for preparation of anti-reflection films, high reflection films and energy saving films and in the field of building coated film products.

Description

technical field [0001] The invention relates to the field of glass, in particular to a coated glass and its application. Background technique [0002] At present, in the magnetron sputtering coating process, the coating is mainly divided into a metal layer and a non-metallic medium interference layer; the interference layer material is usually silicon nitride, zinc tin oxide, zinc tin antimony oxide, tin oxide, zinc aluminum oxide, titanium oxide and other substances, and the existing research mainly focuses on improving and changing the material of the dielectric layer in the film layer. [0003] Due to the reasons of technology and cost, the cathode target material for manufacturing the dielectric layer is usually metal or metal alloy. In the coating process, the magnetron sputtering process is usually used to sputter the material with ionized process gas argon ions. Here The particles sputtered out during the process react with the incoming reaction gas oxygen or nitroge...
