  • Patent number: 6967060
    Abstract: A coated article is provided so as to include a coating (e.g., low-E coating, or the like) having at least one layer of or including niobium zirconium (NbZr). The NbZr layer may be metallic in certain example embodiments. Alternatively, an oxide and/or nitride of NbZr may be provided in other example embodiments. The NbZr inclusive layer may be provided as any suitable layer of the multi-layer coating, but in certain example instances may be used as a contact layer adjacent to an infrared (IR) reflecting layer. Coated articles herein may be used in the context of insulating glass (IG) window units, laminated windows, architectural or residential monolithic window units, vehicle window units, and/or the like.

  • Publication number: 20050205416
    Abstract: A coated article is provided so as to include a solar control coating having an infrared (IR) reflecting layer sandwiched between at least a pair of dielectric layers. The IR reflecting layer includes niobium nitride (NbxNy). The use of niobium nitride enables the coated article to have good corrosion resistance to acid(s), good mechanical performance such as scratch resistance, and/or good color stability (i.e., a low ?E* value(s)) upon heat treatment (HT). The coated article may be heat treated (e.g., thermally tempered) in certain example embodiments of the invention.

  • Patent number: 6926967
    Abstract: A heat treatable coated article including a solar management layer for reflecting infrared (IR) or the like, is provided between a substrate and an overlying dielectric layer. An underlying dielectric layer between the substrate and solar management layer is optional. In certain embodiments, the solar management layer may include NiCrNx while the dielectric layer(s) may include a nitride such as silicon nitride. By nitriding the solar management layer, it has been found that the resulting coated article is more color stable upon heat treatment (HT). For example, the coated article may have a ?E* value (transmissive and/or glass side reflective) of no greater than 5.0, more preferably no greater than 4.0, and most preferably no greater than 3.0. Coated articles herein may be used in the context of insulating glass (IG) window units, vehicle windows, or the like.

  • Publication number: 20050145480
    Abstract: A coated article is provided so as to have a fairly high visible transmission (TY or Tvis) to sheet resistance (Rs) ratio (i.e., a ratio Tvis/Rs). The higher this ratio, the better the coated article's combined functionality of providing for both good solar performance (e.g., ability to reflect and/or absorb IR radiation) and high visible transmission. In certain example embodiments, coated articles herein may be heat treatable. Coated articles herein may be used in the context of insulating glass (IG) window units, architectural or residential monolithic window units, vehicle window units, and/or the like.

  • Patent number: 6908679
    Abstract: A coated article is provided so as to include a solar control coating having an infrared (IR) reflecting layer sandwiched between at least a pair of dielectric layers. The IR reflecting layer includes NbZr and/or NbZrOx in certain embodiments of this invention. The use of such materials as an IR reflecting layer(s) allows the coated article to have good corrosion resistance to alkaline solutions, good mechanical performance such as scratch resistance, and/or good color stability (i.e., a low ?E* value(s)) upon heat treatment (HT). The coated article may or may not be heat treated in different embodiments of the invention.

  • Publication number: 20050079369
    Abstract: A coated article or layer system is provided which includes at least one infrared (IR) reflecting layer including niobium (Nb) sandwiched between at least a pair of dielectric layers. In certain embodiments, a Cr inclusive barrier layer is provided to protect the Nb inclusive IR reflecting layer, for chemical durability purposes. In other example embodiments, a protective overcoat including a zirconium oxide inclusive layer may be provided to protect the Nb inclusive IR reflecting layer for durability purposes.

  • Publication number: 20050069717
    Abstract: In certain example embodiments, a multi-layer undercoat may include a layer of or including tin oxide on the glass surface and a layer of silicon nitride thereover. Tin oxide is advantageous in that it is relatively durable, and is a low stress material with excellent adhesion to glass. Moreover, the sputtering rate for tin oxide is several times higher than that of silicon nitride. Thus, problems of high cost (due to slow deposition rate) and durability (due to high compressive stress) can be overcome through the use of tin oxide as a bottom portion of the dual layer overcoat. The coated article may or may not be heat treated in different embodiments of the invention.

  • Patent number: 6863928
    Abstract: A heat treatable coated article including an infrared (IR) reflecting layer (e.g., of or including Ag), the coated article being able to attain a ?E* (glass side) no greater than about 3.0, more preferably no greater than 2.5, and even more preferably no greater than 2.0, following or due to heat treatment (e.g., thermal tempering). Accordingly, low-E (i.e., low emissivity) coated articles of certain embodiments of this invention appear from the glass side thereof visually similar to the naked eye both before and after heat treatment. Coated articles herein may be used in the context of insulating glass (IG) window units, vehicle windshields, or any other suitable applications. In certain embodiments of this invention, an exemplary layer stack includes: glass/Si3N4/NiCr/Ag/NiCr/Si3N4. Other materials may instead be used without departing from the scope and/or spirit of the instant invention which is a low-E matchable product.

    Abstract: A coated article, and a corresponding method of making the same are provided. The coated article includes a coating supported by a substrate, the coating including a thin metal or metal nitride contact layer (e.g., NiCr, Ni, Cr, CrNx or NiCrNx) located directly between and contacting an infrared (IR) reflecting layer (e.g., Ag) and an oxide barrier layer (e.g., NiCrOx).
