Barium Fluoride An Excellent High Density Optical Material

Edit:Shanghai TaiYang Technology Co.,Ltd      Date:Oct 24, 2017

Barium fluoride colorless cubic fine crystals. Slightly soluble in hot water, soluble in acid and ammonium chloride. poisonous. In the form of frankdicksonite in nature. Barium fluoride crystals are an excellent high-density optical material with excellent scintillation performance and a good buffer layer that can be connected to semiconductors with different lattice constants. Barium fluoride molecules do not contain oxygen atoms, is used as blast furnace manganese iron desilicon solvent, in the blast furnace ferromanganese desilication to obtain high desilication rate and low manganese oxidation loss rate. Barium fluoride in the development of high temperature superconducting devices have a significant role in the superconducting film (YBaCuO) surface deposition of a layer of barium fluoride as a protective layer of YBaCuO, YBaCuO can maintain the stability.

Barium fluoride is alkaline earth fluoride crystal, colorless and transparent, belonging to the cubic crystal system, face-centered cubic structure type. Is a coordination type crystal, each barium atoms surrounded by eight fluoride ions, constitute anionic cube break structure

Primitive), and F is surrounded by four Ba constitute the tetrahedral structure of the element, Ba in the vertical face of the heart is closely packed.

Solid - state barium fluoride is fluorite - type crystal structure, cubic crystal system. Under high pressure into lead chloride structure.

When the gaseous state exists in the form of BaF molecules, the F-Ba-F bond angle is about 108 °, which is contradictory to the prediction of the mutual electrons of valence electrons. The results of the ab initio calculations show that this is the result of the d orbital participation of the barium atoms. It is also argued that this is caused by the polarization of the inner layer of barium, resulting in a tetrahedral charge distribution around the barium atoms and is associated with the Ba-F bond.

For the manufacture of motor brushes, optical glass, optical fiber, laser generator, flux, paint enamel, but also for wood preservatives and pesticides. For the manufacture of flux, enamel manufacturing; for corpse preservatives, solid lubricants. BaF2 crystals are used as UV or infrared windows and laser materials. Barium fluoride crystals are an excellent high-density optical material with excellent scintillation performance and a good buffer layer that can be connected to semiconductors with different lattice constants. Barium fluoride crystals have excellent scintillation performance and fast time characteristics, making it in nuclear medicine, nuclear physics, particle physics and remote sensing technology and so on more and more widely used. But also has good moisture resistance, the use of high temperature characteristics. Can be used as CO2 laser and other devices and the whole window material and used as other optical components.

Barium fluoride material can effectively promote the preparation of aluminum phosphors for the preparation of YAG: CE phosphor in solid phase. Barium fluoride is also commonly used in low temperature refrigeration thermal imaging systems and can be used as some application substrates. Barium fluoride molecules do not contain oxygen atoms, is used as blast furnace manganese iron desilicon solvent, in the blast furnace ferromanganese desilication to obtain high desilication rate and low manganese oxidation loss rate. Barium fluoride in the development of high temperature superconducting devices have a significant role in the superconducting film (YBaCuO) surface deposition of a layer of barium fluoride as a protective layer of YBaCuO, YBaCuO can maintain the stability. Barium fluoride has a very wide range of applications and scientific applications.
