COATED ARTICLE WITH LOW-EMISSIVE COATING HAVING TITANIUM OXIDE LAYER AND/OR NiCr BASED LAYER(S) TO IMPROVE COLOUR VALUES AND/OR TRANSMISSION, AND METHOD OF MAKING SAME Russian patent published in 2014 - IPC C03C17/36 

FIELD: chemistry.

SUBSTANCE: invention relates to a coated article with a low-emissive coating and specifically to a heat-insulating double-glazed window. Double-glazing enables a double-silver coated article to achieve (i) an LSG value (T_vis/SHGC) of at least 2.0, (ii) an SHGC value of not more than 35%, more preferably not more than 33%, 32% or 30% and (iii) a U-value (BTU h^-1 ft^-2 °F^-1) (e.g., x=12 mm) of not more than 0.30, more preferably not more than 0.28 or 0.25. In certain example embodiments, the titanium oxide based layer may be an interlayer provided in a bottom portion of the layer stack between first and second layers containing silicon nitride. The bottom layer stack which includes titanium oxide may include NiCr based layer(s).

EFFECT: improving b* colour values and/or transmission of the coated article and improving optical properties of the coated article.
