Method of producing independent glass films

Abstract

Methods for producing an independent glass ceramic film including the steps of mixing a colloidal silica sol having a pH of about 4 or less, a zirconium-containing compound, a binder, and a crosslinking agent capable of crosslinking with the binder at about 50° C. or less, to produce a mixed liquid; coating the mixed liquid on a substrate; drying the coated mixed liquid to form a precursor film on the substrate; separating the precursor film from the substrate; and firing the separated precursor film. A precursor liquid that includes colloidal silica sol having a pH of about 4 or less, a zirconium-containing compound, a binder, and a crosslinking agent capable of crosslinking with the binder at about 50° C. or less is also disclosed.
