Abstract
La présente invention concerne un verre d'aluminosilicate de lithium renforcé chimiquement qui se caractérise par une compression de surface d'au moins 100000 psi et une profondeur de cémentation de compression d'au moins 600 microns. Le verre peut également se caractériser par une compression à 50 microns en-dessous d'une surface du verre, qui vaut au moins 30000 psi. L'invention a également pour objet un procédé pour produire ce verre, comprenant la mise à disposition d'un verre d'aluminosilicate de lithium dont la composition comprend (en % en poids) Li2O en une quantité de 3 à 9 %, Na2O + K2O en une quantité inférieure ou égale à 3 %, et AI2O3 en une quantité de 7 à 30 %. La composition confère au verre une température de recuit d'au moins 580 °C. L'invention fait intervenir un bain mixte de sels de potassium et de sodium comprenant une quantité prédominante de sel de potassium. Le rapport entre les moles de sel de sodium et les moles de sel de potassium dans le bain de sels mixte, peut valoir de 1:10 à 1:2. La température du bain de sels est maintenue sur une plage de valeurs de 450 °C à la température de recuit du verre. Le verre est immergé dans le bain de sels pendant une durée de 2 à 96 heures. Le verre de l'invention a une résistance élevée efficace pour résister à la fracturation sous l'effet de la flexion imposée par l'impact de projectiles à vitesse élevée, et comprend: un verre résistant aux balles, un verre résistant aux explosions, un verre pour véhicule de défense blindés, des fenêtres pour bâtiments gouvernementaux, des fenêtres pour monuments, des vitres véhicules, des éléments transparents de train, des éléments transparents d'aéronef, des fenêtres résistant aux ouragans, des fenêtres résistant aux tremblements de terre, des vitres de guichet de banque, des vitrines, et des panneaux tactiles de guichets bancaires automatiques.
