Barium Fluoride An Excellent High Density Optical Material

Colorless cubic fine crystal. Slightly soluble in hot water, soluble in acid and ammonium chloride. Toxic。 In nature the form of fluorine-barium ore (Frankdicksonite) exists. Barium fluoride crystal is an excellent high density optical material with excellent scintillation performance and good buffer layer, which can connect semiconductor with different lattice constants. The oxygen-free atom in barium fluoride molecule is used as the solvent of the blast furnace Ferromanganese, which obtains high decalcification rate and low manganese oxidation loss rate in the process of removing silicon from blast furnace ferromanganese. Barium fluoride plays an important role in the development of HTS devices, and a layer of barium fluoride is deposited on the surface of superconducting thin film (Ybacuo) as a protective layer of ybacuo to maintain ybacuo stability.

Barium fluoride is a alkaline fluoride crystal, colorless and transparent, belongs to the cubic crystal system, the surface of the cubic structure type. is a ligand-shaped crystal, surrounded by eight of fluorine ions around each barium atom, constituting the anion cubic structure

The base element, and the F is surrounded by four BA to form the tetrahedron structure primitive, the BA lies in the upright aspect the heart lattice position is close accumulation.

The solid-state barium fluoride is a fluorite-type crystal structure and cubic crystal system. High-pressure transition to lead-chloride-type structure.

In gaseous state, the f-ba-f bond angle is about 108° in the form of BaF molecule, which contradicts the prediction of mutual exclusion theory by valence-layer electrons. The results from the ab initio show that this is the result of the D orbital involvement of the barium atom. There is also a theory that this is caused by the polarization of the inner layer of barium, which produces a tetrahedral charge distribution around the barium atom, and is associated with the ba-f bond.

Used in the manufacture of electrical brush, optical glass, optical fiber, laser generator, flux, coating agent enamel, but also for wood preservatives and pesticides. Used for making flux, enamel manufacturing; BaF2 crystals are used as ultraviolet or infrared windows and laser materials. Barium fluoride crystal is an excellent high density optical material with excellent scintillation performance and good buffer layer, which can connect semiconductor with different lattice constants. Barium fluoride crystals have excellent scintillation properties and fast time characteristics, which make it more and more widely used in nuclear medicine, physics, particle physics and remote sensing technology. Also has a good resistance to moisture, the use of high temperature characteristics. It can be used as a window material for CO2 lasers and other components and as other optical elements.

Barium fluoride material can effectively promote the preparation of aluminum fluorescent powder, used in solid phase preparation of YAG: CE phosphors. Barium fluoride is also commonly used in cryogenic refrigeration thermal imaging systems and can be used as substrates for certain applications. The oxygen-free atom in barium fluoride molecule is used as the solvent of the blast furnace Ferromanganese, which obtains high decalcification rate and low manganese oxidation loss rate in the process of removing silicon from blast furnace ferromanganese. Barium fluoride plays an important role in the development of HTS devices, and a layer of barium fluoride is deposited on the surface of superconducting thin film (Ybacuo) as a protective layer of ybacuo to maintain ybacuo stability. Barium fluoride has a wide range of applications and scientific application research value.
