About Scandium Oxide |
The production method of Scandium Oxide is mainly oxalic acid precipitation method, that is, taking Scandium chloride or Scandium nitrate solution as raw material, adjusting the Ph value to 2 with oxalic acid, adding ammonia to precipitate scandium oxalate, heating, maturing, separating, washing, drying at 110 ℃, and burning at 900~1000 ℃ to form Scandium oxide. |
