Barium fluoride Chemical Properties,Uses,Production


Barium fluoride (chemical formula: BaF2) is a inorganic salt consisting of barium and fluorine. It appears as a transparent crystal and is presented in the mineral frankdicksonite in nature. Barium fluoride has many applications. It can be used for the manufacturing of optical components such as lenses as well as the windows of infrared spectroscopy. It can also be used as scintillators for detection of X-rays, Gamma rays and other high energy particles. In aluminium-metallurgy, it is used as additive in aluminium refining process. It can also be used as a flux and opacifying agent during the enamel and glazing first production. Moreover, it is also applied in the production of welding agents. Barium fluoride is made through the reaction between barium carbonate with ammonium fluoride.



Barium fluoride appears as colourless, odourless crystals/white powder and is slightly soluble in water but soluble in ethanol and methanol. When heated, barium fluoride decomposes and emits toxic fumes of fluorine and barium. Barium fluoride is used as a preopacifying agent and in enamel and glazing frits production. Its other use is in the production of welding agents (an additive to some fluxes, a component of coatings for welding rods and in welding powders). It is also used in metallurgy as a molten bath for refining aluminium.

Chemical Properties

White Fine Powder

Physical properties

Barium fluoride (BaF2), also known as barium(II) fluoride, is a solid which can also be a transparent crystal. Its molecular weight is 175.34 g/mol. It occurs in nature as the mineral “Frankdicksonite”. It occurs as a white powder with a melting point of 1290 and a boiling point of 2259°C. It is slightly soluble in water (0.159 at 0.0°C and 0.162 g/100 ml of water at 20°C). The solid generally assumes the fluorite structure, but when subjected to high pressure, changes to the PbCl2 structure. In the vapor phase, the BaF2 molecule is nonlinear with an F–Ba–F angle of approximately 108°C.


As a flux and opacifier in vitreous enamels; in the manufacture of carbon brushes for DC motors and generators; in heat-treating metals; in embalming; in glass manufacture.

Safety Profile

A poison by ingestion and intraperitoneal routes. Moderately toxic by subcutaneous route. An experimental teratogen. See also FLUORIDES and BARIUM COMPOUNDS (soluble). When heated to decomposition it emits toxic fumes of F-.

Purification Methods

Wash it well with distilled H2O and dry it in a vacuum. Its solubility in H2O is 1.6g (10o), 1.6g (20o) and 1.62g (30o) per L, and is soluble in mineral acids and aqueous NH4Cl. It may be stored in glass bottles. [Kwasnik in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 234 1963.]
