Barium fluoride is a chemical compound of barium and fluorine. Molecular formula: BaF2. The highest quality Barium Fluoride also has application as the fastest known scintillator material and is used in High Energy Physics Experiments. Barium Fluoride (BaF2) is commonly used as a scintillator material and is useful as a transmission window material for IR spectroscopy particularly for analysis of fuel oil samples. Molecular Weight: 175.34 g/mol.
Barium Fluoride is used as a molten bath component in aluminum raffination, as flux and preopacifying agent and as component of welding rod coatings and welding powders. CAS: 7787-32-8. It occurs innature as the mineral frankdicksonite. Barium fluoride can be used as a material to make optical components such as lenses. It is used eg. in windows for infrared spectroscopy, in particular in the field of fuel oil analysis. For an equivalent thickness the transmission extends approximately 1 micron further into the IR than Calcium Fluoride. This material is extremely sensitive to thermal shock.
Barium fluoride is used for optical windows, prisms and lenses transmitting from the vacuum ultraviolet into the Infrared. BaF? is also a scintillation material that exhibits one of the fastest known decay constants among inorganic materials. It can be used as a material to make optical components such as lenses. It is used in windows for infrared spectroscopy, in particular in the field of fuel oil analysis.
