ABSTRACT:
Disclosed is an ion exchange process and composition useful therein for creating a gradient-index profile in a glass structure which uses a monovalent metal salt bath modified by the addition of a non-monovalent metal salt which provides for complexing of the outdiffusing cation (of the ion exchange process) to prevent poisoning via that cation.
