Abstract:
1. A glazing comprising: a reflective layer deposited by vacuum sputtering, the reflective layer comprising at least one oxide selected from the group consisting of an oxide of Ta, an oxide of Nb, an oxide of Zr, and any mixed oxide of Ta, Nb, Zr, or any combination thereof, wherein a thickness of the reflective layer and any other layers having a refractive index of greater than 2.2 in the glazing are such that, on a sheet of clear “float” glass having a thickness of 4 mm, the glazing has a reflection of at least 20% and a light transmission of at least 60%, and the reflective layer has mechanical, chemical, or both mechanical and chemical resistance comparable to a resistance of a layer obtained by a process comprising pyrolysis for obtaining a product having comparable optical properties.
