About Lutetium Oxide |
The production method of Lutetium oxide is mainly oxalic acid precipitation method, that is, Lutetium(III) chloride or Lutetium(III) nitrate solution is used as raw material, the Ph value is adjusted to 2 with oxalic acid, and lutetium oxalate is precipitated by adding ammonia water, which is heated, matured, separated, washed, dried at 110 ℃, and then burned at 900~1000 ℃ to form lutetium oxide. |
