Abstract
(EN)
Embodiments of this disclosure pertain to glass articles with a glass composition including about 65 mol% or greater SiO2; 8 mol% or greater Al2O3; from about 3.5 mol% to about 16 mol% Na2O; up to about 5 mol% P2O5, and up to about 15 mol% ZnO. In one or more embodiments, the glass composition includes about 56% or greater SiO2; about 8 mol% or greater Al2O3; from about 3.5 mol% to about 16 mol% Na2O; up to about 1 mol% P2O5; and up to about 15 mol% ZnO. In some embodiments, the glass article exhibits a CS at a depth of greater than 30 micrometers of about 1 GPa or greater. Embodiments of an automotive interior system including such glass articles and methods of making glass articles are also disclosed.

Des modes de réalisation de la présente invention concernent des articles en verre ayant une composition de verre comprenant environ 65 % en moles ou plus de SiO2 ; 8 % en moles ou plus d'Al2O3 ; d'environ 3,5 % en moles à environ 16 % en moles de Na2O ; jusqu'à environ 5 % en moles de P2O5, et jusqu'à environ 15 % en moles de ZnO. Dans un ou plusieurs modes de réalisation, la composition de verre comprend environ 56 % ou plus de SiO2 ; environ 8 % en moles ou plus d'Al2O3 ; d'environ 3,5 % en moles à environ 16 % en moles de Na2O ; jusqu'à environ 1 % en moles de P2O5 ; et jusqu'à environ 15 % en moles de ZnO. Dans certains modes de réalisation, l'article en verre présente une contrainte de compression CS à une profondeur supérieure à 30 micromètres d'environ 1 GPa ou plus. Des modes de réalisation concernent également un système intérieur d'automobile comprenant de tels articles en verre et des procédés de fabrication d'articles en verre.
