Method for the manufacture of a tempered and/or curved glass pane with reduced transmission

Abstract

Abstract Method for the manufacture of a prestressed and/or curved glass pane of soda-lime-silica glass having reduced transmission in a prescribable spectral range (in prescribable spectral ranges), in particular a sunshade pane, whereby at least one metal layer having a majority content of a metal or of a metal alloy from the elements having the atomic numbers 22 through 28 of the periodic table is applied to at least one side of a glass carrier and a protective layer of at least one metal oxide or mixed metal oxide is applied to that side thereof facing away from the glass carrier, and whereby a thermal prestressing and/or bending process is carried out in air at a temperature of 580° C. through 680° C., preferably 600° C. through 650° C., characterized in that both the metal layer as well as the protective layer are applied to the essentially planar glass carrier before the thermal prestressing and/or bending process; and in that the protective layer is applied with an oxygen deficit x, referrred to a metal atom of the metal oxide or, respectively, oxides, of 0.05≦x≦0.4 and in a thickness from 10 nm through 100 nm, being applied in such a composition that no noteworthy oxygen diffusion into the metal layer occurs during the prestressing and/or bending process.
