Sodium bifluoride
Product Basic Parameter of Physical Chemistry:
Product name: Sodium bifluoride (NaHF2)
Molecular weight: 61.99
English name: sodium bifluoride,Sodium hydrogen fluoride
Characters: It is a colorless or white crystal with relative density of 2.08. It has strong sourness. It is soluble in water, but insoluble in alcohol. In humidity air it absorbs moisture and releases hydrogen fluoride. When heated to 160°C it decomposes into sodium fluoride and hydrogen fluoride. At high temperature aluminium and aluminium alloy can resist the corrosion of hydrogen fluoride. Its aqueous solution can etch glass. It is toxic.

Quality standard:
Main content Chloride(Cl) Silicon dioxide(SiO2) Sulphate(SO4)
=98% =0.1% =0.5% =0.1%
Free acid(HF) Water-insoluble matter Water(H2O)
=0.2% =0.5% =0.5%

Packing:Packing with plastic weave bag lined with polythene plastic bag,25kg per bag.
