Boron trifluoride, an inorganic compound, is a colorless gas, soluble in cold water, concentrated sulfuric acid and most organic solvents. Boron trifluoride (BF3) is a colorless and pungent gas at room temperature, can not burn, can not help combustion, 1.3 times heavier than air, mixed with wet air to produce white smoke, its purity is higher than 99.6%. Boron trifluoride corrodes glass at room temperature, but wet boron trifluoride is highly corrosive.


It is used primarily as a catalyst in organic synthesis and also as a high energy fuel for rockets.

BF3 is used as a catalyst in organic synthesis, as a raw material for the synthesis of organic borides, and also used in nuclear technology and optical fiber.

In the electronics industry, it is mainly used as P-type dopant, particle into source combined plasma etching gas. BF3 and the compound are used as curing agents in epoxy resins. It is also used as a lubricant for cast steel.
