Prdouct Details:

Fluoroboric acid

Fluoroboric acid or tetrafluoroboric acid is an inorganic compound with the chemical formula H 3OBF 4.
It is mainly produced as a precursor to other fluoroborate salts. It is a strong acid. Fluoroboric acid is
corrosive and attacks the skin. It is available commercially as a solution in water and other solvents such as
diethyl ether. With a strength comparable to nitric acid, fluoroboric acid is a strong acid with a weakly
coordinating, non-oxidizing conjugate base. It is structurally similar to perchloric acid, but lacks the hazards
associated with oxidants.

Properties:

Fluoroboric acid is a colorless and transparent liquid strong acid. It can exist inFluoroboric acid a pure.
It can only exist in aqueous solution. In general the industrial product is about 42-48% of aqueous
solution. Its relative density is 1.32-1.37, Fluoroboric acid is steady in concentrated solution. It can be
resolved when it is heated to 130°C. It can mix and dissolve with water or alcohol. The product is toxic
and very corrosive.

 

Application:

The product is often used as organic synthetic catalyst or as cleaning agent filmr-Emving agent and
polishing compound compound on the surface of metal aluminium and stainless steel in a fluoroborate
electroplating trough, and also used as chemical remover for lead and tinning layer. In petroleum
industry, HBF4 can be used as acidification for siliceous oil rock well.

 

Storage:                            It should be stored in a cool and ventilated storehouse.

Transport:                         The product belongs to Grade B inorganic acid corrosive goods. It should be kept away from the rain and the
sunlight during its transportation.
