Molecular formula: NaHF2
Molecular weight:
61.99
Physical and chemical feature: It is a white powder crystal
with toxicity. It is dissolved in water with strong acid smell. its specific
gravity is 2.08. In wet air, it can absorb moisture and give out hydrogen
fluoride it can decompose into natrium fluoride and hydrogen fluoride when being
heated. With high temperature, aluminium and aluminum alloy have the function of
controlling the corrosion of NaHF2.
