Quick Summary

The ZBLAN group refers to a type of heavy-metal fluoride glass (HMFG) that has potential applications in telecommunications fibers due to its low optical losses. However, these glasses are challenging to manufacture and have poor chemical durability.1

Barium fluoride (BaF2) is a white, crystalline compound used in optics, such as in lenses, and as a flux in some enamels. It is a component of the ZBLAN group, which also includes fluorides of zirconium, lanthanum, aluminum, and sodium.21
