Barium fluoride chemistry Properties,Uses,Production

Description

Barium fluoride (chemical formula: BaF2) is a not natural salt consist of of barium and also fluorine. It appears as a transparent crystal and is presented in the mineral frankdicksonite in nature.Barium fluoride has plenty of applications. It can be supplied for the manufacturing of optical materials such together lenses and also the windows of infrared spectroscopy. That can also be supplied as scintillators because that detection that X-rays, Gamma rays and also other high energy particles. In aluminium-metallurgy, that is offered as additive in aluminium refining process. The can also be supplied as a flux and also opacifying agent throughout the enamel and glazing very first production. Moreover, that is likewise applied in the production of welding agents. Barium fluoride is made through the reaction in between barium carbonate v ammonium fluoride.

Description

Barium fluoride appears as colourless, odourless crystals/white powder and also is slightlysoluble in water but soluble in ethanol and methanol. As soon as heated, barium fluoridedecomposes and emits toxic fumes the fluorine and also barium. Barium fluoride is offered asa preopacifying agent and also in enamel and glazing frits production. Its various other use is in theproduction the welding agents (an additive to some fluxes, a ingredient of coatings forwelding rods and also in welding powders). It is likewise used in metallurgy as a molten bath forrefining aluminium.

Chemical Properties

White Fine powder

Physical properties

Barium fluoride (BaF2), likewise known as barium(II)fluoride, is a solid i beg your pardon can also be a transparentcrystal. Its molecular weight is 175.34 g/mol. That occursin nature as the mineral “Frankdicksonite”. It occurs asa white powder with a melting allude of 1290 and a boiling allude of 2259°C. That is slightly dissolve in water(0.159 at 0.0°C and 0.162 g/100 ml the water in ~ 20°C). The solid typically assumes the fluorite structure, butwhen subjected to high pressure, changes to the PbCl2structure. In the vapor phase, the BaF2 molecule isnonlinear v an F–Ba–F edge of around 108°C.

Uses

as a flux and also opacifier in vitreous enamels; in the manufacture of carbon brushes because that DC motors and generators; in heat-treating metals; in embalming; in glass manufacture.

Safety Profile

A toxicity by ingestionand intraperitoneal routes. Moderately toxicby subcutaneous route. One experimentalteratogen. See also FLUORIDES andBARIUM compound (soluble). Whenheated to decomposition it emits toxicfumes the F-.

Purification Methods

to wash it well with distilled H2O and also dry it in a vacuum. That is solubility in H2O is 1.6g (10o), 1.6g (20o) and also 1.62g (30o) per L, and also is soluble in mineral acids and also aqueous NH4Cl. It may be save on computer in glass bottles.
