Abstract
A temperature-resistant glass or glass-ceramic pane is provided. The pane includes a substrate and a tin-oxide layer comprising antimony deposited on the substrate.
Claims12
A glass-ceramic pane, comprising a tin-oxide reflection layer comprising between 2 and 6 weight percent antimony oxide, the layer being deposited by using a sputtering method on a green glass blank that is ceramicized by a ceramicizing process after the deposition of the layer to form the pane such that the pane has a reflectance of more than 30% at a wavelength between 3000 and 4000 nm and an average transmittance in the region of visible light of more than 40%.
A glass-ceramic pane comprising:
- a heat tempered tin-oxide layer that reflects infrared radiation that is applied by using a sputtering method and that comprises between 2 and 6 weight percent antimony, the tin-oxide layer being transparent in the visible region;
- and
- a glass-ceramic substrate being shaped after application of the tin-oxide layer to the glass-ceramic substrate and during ceramicizing of the substrate.
An oven comprising a glass-ceramic pane with a tin-oxide reflection layer comprising between 2 and 6 weight percent antimony oxide, wherein the tin-oxide reflection layer reflects infrared radiation and is transparent in a region of visible light.
