It is a mixture obtained by reaction of the pentafluoride of Antimoine with the hydrofluoric Acid $\backslash \; rm\; \{SbF\_5+2HF\}$ and whose chemical formula is: (SbF₆) ⁻, (H₂F) ⁺. It is approximately 2×10¹⁹ time more corrosive than the sulphuric Acid . That is to say 20 billion more corrosive billion. It is very toxic and volatile, therefore difficult to use.
