HIGH INFRARED TRANSMISSION GLASS SHEET |
| 摘要 |
The invention relates to a glass sheet with high IR transmission. More precisely, the invention relates to a glass sheet having a composition comprising in a content expressed in percentages of the total weight of the glass: 55≦SiO2≦85% 18<Al2O3≦30% 0≦B2O3≦20% 0≦Na2O≦25% 0≦CaO≦20% 0≦MgO≦15% 0≦K2O≦20% 0≦BaO≦20% 0.002≦total iron (expressed in the form of Fe2O3)≦0.06%, said composition comprising a chromium content such as: 0.0001%≦Cr2O3≦0.06% expressed in a percentage of the total weight of glass. Because of its high IR transmission the glass sheet according to the invention can be advantageously used, for example, in a screen or panel or pad, wherein the glass sheet defines a touch sensitive surface. The invention also relates to the use of such a glass sheet in a device using an infrared radiation that propagates essentially inside said sheet. |
