Abstract: Thermostable mirrors comprise an optically transparent glass substrate and a thermostable mirror coating on a surface of the substrate. The mirror coating has a reflective chromium-based layer (formed of Cr or Ni—Cr) which preferably is used with reflectivity enhancing layer of silver or copper metal. Such reflectivity enhancing layer can be sandwiched between chromium-based layers. Optical color may be provided by a color-forming oxide layer, such as a layer of CuOx between the glass substrate and the reflective layer(s). The reflective coating is thermostable at the tempering temperature of the glass. The coating provides controllable reflectivity and, optionally, controllable color properties, which are substantially stable through exposure of the substrate to tempering and bending temperatures. In accordance with a method of manufacturing the coated article, the thermostable coating is deposited by D.C. magnetron sputtering in a multi-station sputtering chamber.

Abstract: A heat-treatable coated glass article comprises a substantially transparent substrate with a substantially transparent dual-function coating on a surface of the substrate. The coating provides low emissivity and high anti-solar performance properties. It comprises a first anti-reflection layer of dielectric material, preferably tungsten oxide. An infra-red reflective layer of silver metal and/or copper metal overlies the anti-reflection dielectric layer. A buffer layer, such as a chromium buffer layer, is positioned between the anti-reflection layer and the infra-red reflective layer. Also, optionally, a color control layer may be used, preferably being positioned between the anti-reflection layer and the substrate. A second buffer layer directly overlies the infra-red reflective layer. A second anti-reflection layer overlies the second buffer layer. In accordance with a method of manufacturing the coated article, each of the layers of the coating is deposited in turn by D.C.
