Application: Colored alkali aluminosilicate glass articles (Patent ID: US20240199470A1)
The patent filed by Corning Inc. describes a glass article with a specific composition, including SiO2 and various other components, along with a colorant to impart a preselected color. The glass undergoes ion exchange to create compressive stress on the surface, with the colorant either part of the glass batch or the ion exchange bath, containing metal-containing dopants for coloration, such as transition and rare earth metals.
The patent claims detail the specific composition of the colored glass, including SiO2, Al2O3, B2O3, MgO, ZnO, P2O, and alkali metal oxides, along with colorant dopants like Au, Ag, Cu, and others. The glass is strengthened through ion exchange, with specific requirements for compressive stress and depth of layer. The colorant dopants may include Cu and Cr, with limitations on the amounts of Fe2O3, Co3O4, and CuO present in the glass. The claims also outline variations in the composition of the glass and colorant dopants, emphasizing the importance of specific components and their concentrations for the desired properties in the colored glass article.
