COATED ARTICLE WITH AN IR-REFLECTING LAYER OR LAYERS AND A ZIRCONIUM-SILICON OXYNITRIDE LAYER OR LAYERS Russian patent published in 2022 - IPC C03C17/36 

FIELD: layered products.

SUBSTANCE: invention relates to coated articles usable in relation to insulating glass units or in other corresponding fields of application, in particular, in solid windows, multilayer windows, or in other similar areas. Coating with a low emission coefficient includes a first and a second infrared (IR) emission-reflecting silver-containing layers. The second silver-containing layer is therein at least 10 angstrom thicker than the first one. The coating includes a lower dielectric part including a zirconium-silicon oxynitride-containing layer, and a middle dielectric part including a zinc stannate-containing layer. The configuration of the coating is designed to implement a combination of a preferred transmission coefficient in the visible spectral range, consistent low values of the emission coefficient, thermal stability during additional heat treatment, e.g., during thermal tempering, a preferred value of heat conductivity U, a preferred value of LSG selectivity for the multilayer protective glass, and achievement of preferred values of staining and (or) reflection coefficient. In particilar examples of implementation, an absorbing layer may be located between the pair of dielectric layers.

EFFECT: creation of a coated article suitable for use in windows.
