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 eth-er. 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. Used as acetaldehyde synthesis catalysts, the metal surface cleaning agents, lead electrolytic polishing agents, the diazonium salt stabilizer, etc.Used for cleaning metal surface oxide, silicate film and as a corrosive, for cleaning before aluminum and alloy electroplating. 2.5% solution is for electrolytic polishing of pure aluminum and used as rewashing lotion for removing flux and electroplating parts from the metal substrate, as a catalyst for alkylation and polymerization, preservatives, chemical reagents, as well as the starting materials for preparing various fluoborates.

Used to clean metal and alloy surfaces prior to plating.

Used for preparing stabilized diazonium salts, manufacturing acetal catalyzed, used as an agent for determination of sodium in the presence of potassium ions and magnesium ions, a catalyst in organic synthesis, but also used for the sponge titanium and its alloys-dissolution and the printed wiring board industry.
