摘要 |
<p>The invention relates to a glass panel, including at least one reflective layer deposited by cathode sputtering, said layer consisting of one or more oxides of one of the metals including Ta, Nb, Zr or the mixed oxides of said metals, the thickness of the layer in question and optionally other layers present in the assembly having a refractive index greater than 2.2 being selected such that, on a 4-mm thick sheet of clear "float" glass, said layer(s) result(s) in a reflection of at least 15% and a light transmission of at least 60%, the layer or system of layers in question further having a mechanical and/or chemical resistance comparable to those of layers produced by pyrolysis for obtaining products having the same type of optical properties.</p> |
