ABSTRACT:
Halogen glass is treated, while heated above its fusion temperature, with carbon disulphide. The resulting halogen glass is essentially free of parasitic absorption bands in the infra-red spectrum. The treatment with carbon disulphide apparently lowers the hydroxyl ion content and the metal-oxygen bonds sufficiently to avoid the infra-red absorption bands.
