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% 0≦̸Al2O3≦̸30% 0≦̸B2O3≦̸20% 0≦̸Na2O≦̸25% 0≦̸CaO≦̸20% 0≦̸MgO≦̸15% 10<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. |
