Applications

It finds applications in ceramic flux, glass manufacturing, metallurgy, electronics and dry-film lubricants. It is transparent from ultraviolet to infrared. Barium fluoride is usually employed as a scintillator material, and useful as a transmission window material for IR spectroscopy, mostly used for analysis of fuel oil samples. Of all the optical fluorides, it is the most resistant to high-energy radiation. It is used as a preopacifying agent, and in the production of enamel, welding agents, and glazing frits.

Notes

This material is very sensitive to thermal shock. It should be kept away from mineral acids and strong oxidizers.
