ABSTRACT:
Mercury thallium fluorophosphate glasses are disclosed that have very low transition temperatures, very high refractive indices and dielectric constants, and are resistant to moisture attack. The glasses are free of alkali metals and substitute thallium chloride in the glass batch as a modifier. The melted glass is largely oxide in nature, but the halogens appear to facilitate melting of these soft glasses.
