Method for the production of coated glass with a high transmissivity in the visible spectral range and with a high reflectivity for thermal radiation

Method for the production of coated glass with a high transmissivity in the visible spectral range and with a low surface electrical resistivity and a high reflectivity for thermal radiation by cathode sputtering of coatings on a substrate consisting of mineral glass, the cathode sputtering comprising providing on the mineral glass:

• a) a first coating comprising at least one oxide from the group consisting of tine oxide, silicon dioxide, aluminum oxide, tantalum oxide and zirconium oxide,
• b) a second coating of an alloy of about 80 weight-percent nickel and about 20 weight-percent of chromium,
• c) a third coating of silver or silver alloy containing at least 50 weight-percent of silver,
• d) a fourth coating of the alloy forming the second coating, and
• e) a fifth coating of an oxide form the oxides forming the group of said first coating,
• the substrate then being heated with the coatings a) through e) on it to at least the softening temperature of the glass, plastically shaped in the heated state, and cooled in the shaped state.
