SUBSTRATE SUPPLIED WITH A KIT WITH THERMAL PROPERTIES, CONTAINING AT LEAST ONE LAYER, CONTAINING SILICON-ZIRCONIUM NITRIDE, ENRICHED WITH ZIRCONIUM AND ITS APPLICATION

摘要

The invention relates to a transparent substrate (30) equipped, on a main face, with a stack of thin layers including a single functional metal layer (140) with reflective properties in the infrared and/or in the solar spectrum, in particular based on silver or a metal alloy containing silver, and two antireflection coatings (120, 160), said antireflection coatings each including at least one dielectric layer (122, 128; 162, 168), said functional layer (40) being placed between the two antireflection coatings (20, 60), characterised in that the antireflection coating (120) located between said substrate (30) and said functional layer (140), or even the two antireflection coatings (120, 160) includes/include a layer (126, 166) including silicon-zirconium nitride, Si_xZr_yN_z, with an atomic ratio of Zr over the sum Si+Zr, y/(x+y), that is comprised between 25.0% and 40.0% including these values, or even between 27.0% and 37.0% including these values.
