Abstract
(EN)
Provided is a glass product which has a shape other than a flat plate shape and has a glass composition comprising, represented in mass% on an oxide basis, 60 to 70% of SiO2, 6 to 18% of Al2O3, 2 to 8% of Li2O, 8 to 20% of Na2O, 0 to 1% of K2O, 0 to 3% of MgO, 1 to 6% of CaO, and 0.01 to 0.2% of Fe2O3. This glass composition is suited for being made into a three-dimensional shape using a mold press method and for being strengthened by a chemical strengthening process.
(FR)
L'invention concerne un produit en verre qui a une forme autre qu'une forme de plaque plate et a une composition de verre comprenant, représenté en % en masse sur une base d'oxyde, de 60 à 70% de SiO2, de 6 à 18% d'Al2O3, de 2 à 8% de Li2O, de 8 à 20% de Na2O, de 0 à 1% de K2O, de 0 à 3% de MgO, de 1 à 6% de CaO, et de0,01 à 0,2% de Fe2O3. Cette composition de verre est appropriée pour être transformée en une forme 3D à l'aide d'un procédé de moulage par compression et pour être renforcée par un procédé de renforcement chimique.
