ARTICLE COVERED BY LOW-EMISSION COATING INCLUDING ZIRCONIUM OXIDE AND/OR ZIRCONIUM-SILICON OXINITRIDE Russian patent published in 2013 - IPC C03C17/36 

FIELD: chemistry.

SUBSTANCE: invention relates to coating including at least one material layer reflecting IR radiation, say, silver or the like, in low-emission coating. Coated article includes first dielectric layer, for example, silicon nitride, first contact layer, for example, nichrome, layer reflecting IR radiation including silver, second contact layer containing Ni and/or Cr arranged there above and in contact with reflecting layer, second dielectric layer bearing silicon nitride. Said article comprises at least one outer layer bearing zirconium oxide (for example ZrO₂) or zirconium-silicon oxinitride (for example, ZrSiO_xN_y). Coated articles can be used as isolation glass in wall block windows, vehicle windows, laminated glass windows, or the like.

EFFECT: better chemical and thermal stability ay heat treatment.
