ARTICLE WITH COATING WITH IR-REFLECTING LAYER AND METHOD OF ITS MANUFACTURING Russian patent published in 2020 - IPC C03C17/36 

FIELD: technological processes.

SUBSTANCE: invention relates to articles with a coating for glazing and can be used as a window unit, monolithic window or car window. Coated article comprising a coating resting on a glass substrate, wherein the coating contains, as the distance from the glass substrate: a dielectric layer containing zirconium-silicon oxynitride; a layer containing titanium oxide; a layer containing zinc stannate; a layer containing zinc oxide, located above and directly in contact with a layer containing zinc stannate; an infrared-reflecting layer (IR) containing silver placed on the substrate on top and directly in contact with a layer containing zinc oxide; and a layer containing a metal oxide located on top of at least the said IR-reflecting layer containing silver. Coating contains only one infrared reflecting layer based on silver. Besides, the coating has normal emitting capacity (E_n) of not more than 7 %, and measured as a monolithic coated article has visible light transmittance of at least 75 %.

EFFECT: disclosed invention enables to provide a highly transparent article with a coating which is thermally stable in optional heat treatment and which can be made so that it has low emissivity in a continuous manner, as well as the coating is designed so that it has improved quality of the IR-reflecting layer, and consequently, reduced tolerances with respect to the possibility of obtaining the desired emissivity values.
