Claims
- 1. Method for the production of sheets of mineral glass with high transmission in the visible spectral range and with low solar energy transmission, comprising: cathode sputtering a coating onto a sheet of glass in a coating chamber by cathode sputtering from a target of an alloy of 65% tin and 35% nickel in an atmosphere with an oxygen content to thus form a Sn-Ni suboxide coating on the glass and then heating the glass and coating in air to a temperature of about 640.degree. C. temper the coated glass, the tempering resulting in a stable and electrically conductive combination for said coating; the coating and tempering steps resulting in the providing of a sheet of mineral glass with high transmission in the visible spectral range and low solar energy transmission.
- 2. Method according to claim 1, in which the amount of oxygen in the coating chamber is correctly adjusted when the optical transmission of the sputtered-on coating, after heating the coating to 640.degree. C., shows a saturation value, independently of the heat treatment time ranging from 5 to 20 minutes.
- 3. Method according to claim 1 comprising: applying a protective coating of a metal oxide onto the tin nickel suboxide coating.
- 4. Method according to claim 3, comprising: applying a transparent metal oxide coating onto the glass prior to the cathode sputtering.
