A colorless and transparent cubic or white powder. Dissolved in hydrochloric acid, nitric acid, hydrofluoric acid and ammonium chloride solution, as well as methanol, ethanol organic solvent, slightly soluble in water. The relative density is 4.83. The melting point is 1368 degrees centigrade. The boiling point is 2260 degrees centigrade. The refractive index (n25D) 1.471. Medium toxicity, median lethal dose (rat, oral) 250mG/kG

Colourless cubic crystals. It dissolves in hot water and dissolves in acid and ammonium chloride. It is poisonous. In nature, it exists in the form of barium fluoride (frankdicksonite). Barium fluoride crystal is an excellent high-density optical material with excellent scintillation performance. It is also a good buffer layer, which can connect semiconductor with different lattice constants. Barium fluoride molecules do not contain oxygen atoms, was used as the blast furnace ferromanganese silicon solvent, manganese oxide has high silicon loss rate and low rate in the blast furnace ferromanganese silicon removal. Barium fluoride plays an important role in the development of high temperature superconducting devices. A layer of barium fluoride is deposited on the surface of superconducting thin films (YBaCuO) as a protective layer of YBaCuO, which can maintain the stability of YBaCuO.
