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