Fluoboric Acid - 42-48% Aqueous Solution | Colorless Transparent Liquid, Toxic, Strong Acid, Non-glass Etching

We are engaged in offering excellent quality Fluoboric Acid to our valuable clients.
Molecular formula: HBF4
Cas#:16872-11-0
Molecular weight:87.81
Performance and property: It is colorless transparent liquid. It is a strong acid, and can't exist in pure state and can only exist in aqueous solution. The commercial product is commonly an aqueous solution of about 42-48%. The relative density of 42% aqueous solution is 1.32, and 48% aqueous solution 1.37. It decomposes when heated to 130A C. It can mix with water and alcohol. It decomposes slowly to release hydroxyfluoroboric acid(HBF3OH) in aqueous solution. Its stability decreases gradually once it touches glass. The hydrolysis degree of the 0.047M fluoroboric acid solution increases from 20.6% to 72% when it is kept in glass bottle for 32 days. It has strong causticity, but does not etch glass at room temperature. It reacts with metal element, metal fluoride, oxide, hydroxide or carbonate to form corresponding fluoroborate. It is toxic.
