氟化镱制备

1.氟化氢气体氟化法。这是一种干式氟化法。最佳反应温度为700℃。反应时间8h。反应在回转窑式氟化炉内进行。干燥氟化氢的消耗量约为理论量的2.5倍。制得的高质量氟化物中氧含量在0.04%～0.1%内，转化率可达99％，回收率高于98％。此法操作中要注意对强腐蚀性氟化氢气体的防护。

2 氟化氢铵氟化法。这也是一种干式氟化法。它用氟化氢铵作氟化剂直接与镱的氧化物作用，制得无水氟化镱，将氧化镱与过量30％的试剂纯氟化氢铵均匀混合，盛入铂舟内，然后放入镍铬合金管中，在电阻炉内加热，在300℃下进行氟化，保温12h,氟化反应完成后，升高炉温，在400～600℃的高温下通入干燥的空气或氮气气流，以排除反应后过剩的氟化氢铵蒸气和反应过程中生成的氟化铵与水蒸气。为了避免在高温下可能造成氟化镱发生水解，也可以在真空下除去这些气体产物。
