Ammonium hydrogen difluoride Usage And Synthesis
Chemical Properties white scales or flakes
General Description Ammonium bifluoride solution is the white crystalline solid dissolved in water. Ammonium hydrogen difluoride is corrosive to metals and tissue. Ammonium hydrogen difluoride is used in ceramics.
Air & Water Reactions Dissolves in water and forms a weak solution of hydrofluoric acid.
Reactivity Profile AMMONIUM BIFLUORIDE reacts violently with bases. In presence of moisture will corrode glass, cement, and most metals. Flammable hydrogen gas may collect in enclosed spaces. Do not use steel, nickel, or aluminum containers [USCG, 1999].
Health Hazard TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
