  • Method for producing glass of high transmission in the visible spectral range and low solar energy transmission
    Patent number: 5090984
    Abstract: In a method for the production of sheets of mineral glass with high transmission in the visible spectral range and with low solar energy transmission, a coating is sputtered onto the sheet in a coating chamber by cathode sputtering with a target of an alloy of 65% tin and 35% nickel in an atmosphere with an oxygen content. The sheet and coating are then heated at 640.degree. C. and then bent in the heated state, thus producing an especially stable and electrically conductive combination.
