SHEET OF GLASS WITH HIGH INFRARED RADIATION TRANSMISSION |
| 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:;SiO255-78% Al2O30-18%B2O30-18%Na2O0-20%CaO0-15%MgO0-10%K2O0-10%BaO0-5% total iron (expressed in the form of Fe2O3)0.002-0.4%
and chromium in a content such as: 0.0001%<Cr2O3<0.002%, expressed in percentages of the total weight of glass. 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. 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. |
