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