Barium fluoride is a kind of cubic fine crystallization. Slightly soluble in hot water, soluble in acid and ammonium chloride. Poisonous. In the nature in the form of fluorinated barium ore (frankdicksonite).
Substance use
Used in the manufacture of motor brush, optical glass, optical fiber, laser generator, fluxing agent, coating agent enamel, also can make wood preservatives and pesticides. Used for flux, enamel manufacturing; Used as embalming fluid and solid lubricant. BaF2 crystals used as ultraviolet or infrared and laser window materials. Barium fluoride crystal is a kind of excellent high density optical materials, excellent performance, is also a good buffer layer, can connect different semiconductor lattice constant. Barium fluoride crystals with excellent performance and fast scintillation characteristics of time, to make it in nuclear medicine, nuclear physics, particle physics, and the use of remote sensing technology, etc, more and more widely. Also has the wave resistance is good, use high temperature etc. Can be used for CO2 laser device and window materials and used for other optical components of the machine.
Barium material can effectively promote the preparation of aluminium fluoride type fluorescent powder, used in solid phase of YAG: CE phosphors. Barium fluoride is also commonly used in cryogenic refrigeration thermal imaging system and can be used as substrate in some applications. Barium fluoride containing no oxygen atoms in molecules, be used as blast furnace ferromanganese silicon solvent, in the blast furnace ferromanganese desilication in high desilication rate and low loss rate of manganese oxide. Barium fluoride have a significant role in the development of high temperature superconducting device, in the superconducting thin film deposition (YBaCuO) surface protective layer of a layer of barium fluoride as YBaCuO, can maintain the stability of the YBaCuO. Barium fluoride has a very broad application field and scientific research value.
