Detailed description

Fluoboric Acid

Product Basic Parameter of Physical Chemistry:

Product name:	Fluoboric Acid (HBF₄)
Molecular weight:	87.81
English name:	fluoboric acid,Hydrofluoroboric acid, Tetrafluoroboric acid
Characters:	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 130°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.

Quality standard:

Packing: Packing with polythene plastic barrel,25kg or 250kg per barrel.
