· JVASP-39858· YbF2

Ytterbium fluoride (YbF₂) is a rare-earth fluoride ceramic compound that exhibits high optical transparency in the infrared spectrum and excellent chemical stability. It is primarily used in specialized optics, laser systems, and high-temperature environments where infrared transmission and thermal durability are critical; its rare-earth composition makes it valuable in scientific research and advanced photonics applications where conventional optical materials fall short.
