Barium fluoride can be used to make motor brush, optical glass, optical fiber, laser generator, flux, coating enamel, as well as wood preservative and insecticide. Used for making flux and enamel; used as body preservative and solid lubricant. BaF2 crystal is used as ultraviolet or infrared window and laser material. Barium fluoride crystal is also an excellent high-density optical material with excellent scintillation performance and a good buffer layer, which can connect some semiconductors with different lattice constants. Barium fluoride crystal has excellent scintillation performance and fast time characteristic, which makes it more and more widely used in nuclear medicine, nuclear physics, particle physics and remote sensing technology. It also has good moisture resistance and high temperature. It can be used as the window material of CO2 laser and other devices, as well as other optical elements.
Barium fluoride can effectively promote the preparation of aluminum phosphor, which can be used in solid-state synthesis YAG:CE Phosphor. Barium fluoride is also commonly used in low-temperature refrigeration and thermal imaging systems and as a substrate for some applications. Barium fluoride, which does not contain oxygen atoms, is used as a desilication solvent for blast furnace ferromanganese to obtain high desilication rate and low manganese oxidation loss rate. Barium fluoride plays an important role in the development of high temperature superconducting devices. Depositing a layer of barium fluoride on the surface of superconducting thin film (YBaCuO) as the protective layer of YBaCuO can maintain the stability of YBaCuO. Barium fluoride has a very wide range of applications and scientific research value.
