INFRARED TRANSMITTING MATERIAL CONSISTING OF SILVER CHLORIDE AND SILVER BROMIDE

摘要

Infrared fibers excellent in elongation as well as tensile strength and yield strength, which comprise a mixed crystal containing 0.01 to 10% by weight of silver chloride in silver bromide or a mixed crystal containing 0.01 to 10% by weight of silver bromide in silver chloride. The invention includes an infrared fiber comprising a fiber of the invention enclosed in a protective layer (3) and also an infrared fiber comprising a core (1) consisting of a mixed crystal containing up to 10% by weight of silver chloride in silver bromide and a cladding (2) consisting of a mixed crystal containing up to 10% by weight of silver bromide in silver chloride.
