Title
(EN) LOW TEMPERATURE CHEMICAL STRENGTHENING PROCESS FOR GLASS
(FR) PROCÉDÉ DE RENFORCEMENT CHIMIQUE À BASSE TEMPÉRATURE POUR LE VERRE
Abstract
(EN)
A method of chemically strengthening a glass. The method includes heating an ion exchange solution to a temperature less than about 360 C, and contacting the glass and the strengthening solution at the temperature for a duration from about 0.5 hours to about 24 hours. The ion exchange solution includes a primary nitrate and at least one monovalent or divalent cation nitrate component in an amount from about 1 wt.% to about 10 wt.%.
(FR)
L'invention concerne un procédé de renforcement chimique du verre. Le procédé comprend le chauffage d'une solution d'échange d'ions à une température inférieure à environ 360 °C, et la mise en contact du verre et de la solution de renforcement à cette température pendant une durée d'environ 0,5 heure à environ 24 heures. La solution d'échange d'ions comprend un nitrate primaire et au moins un composant de nitrate à cation monovalent ou divalent en une quantité d'environ 1 % en poids à environ 10 % en poids.
