Description of Sodium tetrafL

Sodium tetrafluoroborate is an inorganic compound with formula NaBF4. It is a salt that forms colorless or white water-soluble rhombic crystals and is soluble in water (108 g/100 mL) but less soluble in organic solvents.
Sodium tetrafluoroborate is used in some fluxes used for brazing and to produce Boron trifluoride.
