  • Patent number: 7621648
    Abstract: A mirror (e.g., first surface mirror) is provided with a layer of or including chromium nitride (CrNx). In certain example embodiments, the CrNx layer may be the primary reflective layer of the mirror. Surprisingly and unexpectedly, it has been found the addition of nitrogen to the chromium to form CrNx reduces pinhole formations in the resulting layer. In certain example embodiments, the more nitrogen which is introduced into the layer, the smaller the number and/or size of pinholes in the Cr inclusive layer. In certain example embodiments, it has also been found that the addition of nitrogen to Cr may improve durability.

  • Publication number: 20090263596
    Abstract: Example embodiments of this invention relate to a coated article including an infrared (IR) reflecting layer of a material such as silver or the like, for use in an insulating glass (IG) window unit for example. In certain example embodiments, the coating is a single-silver type coating, and includes an overcoat including an uppermost layer of or including silicon nitride and a layer of or including tin oxide immediately under and contacting the silicon nitride based overcoat. In certain example embodiments, the thicknesses of the silicon nitride based overcoat and the tin oxide based layer are balanced (e.g., substantially equal, or equal plus/minus about 10%). It has surprisingly been found that such balancing results in an improvement in thermal cycling performance and improved mechanical durability. In certain example embodiments, the coating may realize surprisingly good substantially neutral film side reflective coloration, and may achieve an improved visible transmission, SHGC ratio and low U-values.
