Abstract:
Chemically temperable glass sheet The invention relates to a glass sheet having a boron-, strontium- and lithium-free glass composition comprising the following in weight percentage, expressed with respect to the total weight of glass: 65≤SiO2≤78% 8≤Na2O≤15% 1≤K2O<6% 1≤Al2O3<3% 2≤CaO<10% 0≤MgO≤6%; as well as a total iron (expressed in the form of Fe2O3) in a content ranging from 0.002 to 0.02% by weight and a K2O/(K2O+Na2O) ratio which is ranging from 0.1 and 0.7. The invention corresponds to an easy chemically-temperable soda-lime-silica type glass composition, which is more suited for use in electronic devices applications.
