Title
(EN) GLASS MATERIAL WITH A HIGH INDEX OF REFRACTION
(FR) MATÉRIAU EN VERRE À INDICE DE RÉFRACTION ÉLEVÉ
Abstract
(EN)
A composition for a glass material comprising, on an oxide basis: one or more network formers chosen from the group of silicon dioxide (SiO2) and phosphorous pentoxide (P2O5); one or more alkali metal oxides chose from the group consisting of lithium oxide (Li2O) and sodium oxide (Na2O); 8 to 15 percent by weight zirconium oxide (ZrO2); and one transition metal oxide consisting of 9 to 45 percent by weight niobium pentoxide (Nb2O5). In an embodiment, the composition consists of: 35 to 60 percent by weight silicon dioxide (SiO2); 9.25 to 15.0 percent by weight lithium oxide (Li2O); 0.5 to 2 percent by weight sodium oxide (Na2O); 8 to 15 percent by weight zirconium oxide (ZrO2); 0 to 3.5 percent by weight phosphorous pentoxide (P2O5); and 9 to 45 percent by weight niobium pentoxide (Nb2O5). In an embodiment, the glass material is a light guide for an augmented reality device.

Une composition pour un matériau en verre comprend, en termes d'oxydes : un ou plusieurs agents réticulants choisis dans le groupe formé par le dioxyde de silicium (SiO2) et le pentoxyde de phosphore (P2O5 ; un ou plusieurs oxydes de métal alcalin choisis dans le groupe constitué par l'oxyde de lithium (Li2O) et l'oxyde de sodium (Na2O) ; 8 à 15 pour cent en poids d'oxyde de zirconium (ZrO2) ; et un oxyde d'un métal de transition constitué de 9 à 45 pour cent en poids de pentoxyde de niobium (Nb2O5). Dans un mode de réalisation, la composition est constituée de : 35 à 60 pour cent en poids de dioxyde de silicium (SiO2) ; 9,25 à 15,0 pour cent en poids d'oxyde de lithium (Li2O) ; 0,5 à 2 pour cent en poids d'oxyde de sodium (Na2O) ; 8 à 15 pour cent en poids d'oxyde de zirconium (ZrO2) ; 0 à 3,5 pour cent en poids de pentoxyde de phosphore (P2O5) ; et 9 à 45 pour cent en poids de pentoxyde de niobium (Nb2O5). Dans un mode de réalisation, le matériau en verre est un guide de lumière pour un dispositif de réalité augmentée.
