Don't have a profile? Potassium tetrafluoroborate is used as an active filler in the preparation of resin-bonded abrasives. It is also used for extraction, refining and processing of metals in the chemical industry. It finds application as additive in alloying industry and welding agent. Further, it is used in the production of fluxing agents for brazing and soldering. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio.

With an accout for my. It arises by the reaction of fluoride salts with the Lewis acid BF 3 or by treatment of tetrafluoroboric acid with base. Safety considerations, however, overshadow this inconvenience. Transition and heavy metal fluoroborates are produced in the same manner as other fluoroborate salts; the respective metal salts are added to reacted boric and hydrofluoric acids. Tin , lead , copper , and nickel fluoroborates are prepared through electrolysis of these metals in a solution containing HBF 4. Potassium fluoroborate is obtained by treating potassium carbonate with boric acid and hydrofluoric acid.

Safety considerations, however, overshadow this inconvenience. With a formula weight of Moreover, in other cases of ostensibly "cationic" complexes, the fluorine atom in fact acts as a bridging ligand between boron and the cationic center.

Tetrafluoroborate

Sodium tetrafluoroborate is an inorganic compound with formula NaBF 4. Sodium tetrafluoroborate is used in some fluxes used for brazing and to produce boron trifluoride. Sodium tetrafluoroborate can be prepared by neutralizing tetrafluoroboric acid with sodium carbonate or sodium hydroxide. Alternatively the chemical can be synthesized from boric acid , hydrofluoric acid , and sodium carbonate: [2]. On heating to its melting point, sodium tetrafluoroborate decomposes to sodium fluoride and boron trifluoride : [4]. It is a source of tetrafluoroborate anion, which is used in organic chemistry for the preparation of salts. Sodium tetrafluoroborate can be used for synthesis of ionic liquids , where tetrafluoroborate is the anion. Contents move to sidebar hide.

Unlike other strong acids like H 2 SO 4 or HClO 4 , the pure solvent free tetrafluoroboric acid more precisely, pure hydrogen tetrafluoroborate H[BF 4 ] does not exist. The term "fluoroboric acid" refers to a range of chemical compounds, depending on the solvent. The solvent can be any suitable Lewis base.
