  • The fluorination of scheelite by ammonium bifluoride

    The interaction of scheelite with ammonium bifluoride is studied. It was shown that the scheelite reacts with NH 4 HF 2 at room temperature in contrast to tungstic oxide and other tungsten compounds. Two complexes are formed (NH 4) 3 WO 3 F 3 and new (NH 4) 2 WO 3 F 2.The compounds obtained are light fluorinated (endothermic peaks at 170 and 90176;C correspondingly).
