Boron trifluoride is the chemical compound with the formula BF3. This pungent colourless toxic gas forms white fumes in moist air. It is a useful Lewis acid and a versatile building block for other boron compounds.
BF3 is manufactured by the reaction of boron oxides with hydrogen fluoride.
Boron trifluoride used in sensitive neutron detectors in ionization chambers and devices to monitor radiation levels in the Earth's atmosphere.
Boron Trifluoride is a non-flammable compressed gas, packaged and shipped in cylinders under high pressure. It is often advantageous to use BF3 in a complexed form so that BF3 can be released under preferred conditions.BF3 complexes are typically liquids or solids and therefore may be more easily managed than the high pressure gas.
