PRODUCT WITH COATING HAVING LOW-EMISSION COATING WITH IR-RADIATION REFLECTING LAYER(-S) AND LAYER WITH HIGH REFRACTIVE INDEX BASED ON NIOBIUM AND BISMUTH AND ITS PRODUCTION METHOD Russian patent published in 2021 - IPC C03C17/36 

FIELD: glazing.

SUBSTANCE: group of inventions relates to coated products intended for use in windows, for example in double-glazed window units, vehicle windows, monolithic windows and/or so forth. A coated product includes coating applied to glass substrate. Coating contains the first transparent dielectric layer on glass substrate, a layer reflecting infrared (hereinafter – IR) radiation containing silver on glass substrate, the second transparent dielectric layer on glass substrate. The layer reflecting infrared (IR) radiation is located above at least the first transparent dielectric layer. The second transparent dielectric layer on glass substrate is located above at least the IR-reflecting layer. At least one of the first and the second transparent dielectric layers is amorphous or essentially amorphous and contains Nb and Bi oxide. The metal content in Nb and Bi oxide is 55-99 atomic % of Nb and 1-45 atomic % of Bi. A method for manufacturing a coated product includes spraying the first transparent dielectric layer onto glass substrate, spraying the layer reflecting infrared (IR) radiation above at least the first transparent dielectric layer, spraying the second transparent dielectric layer above at least the IR-reflecting layer.

EFFECT: increase in the thermal stability of the product.
