用途ファインセラミックス、超電導材料用
使用Neodymium oxide (Nd2O3) is a light-blue powder used to color glass and as a pigment for ceramics. It is also used to make color TV tubes.
調製方法
Neodymium oxide is produced from the two principal rare earth minerals, monazite, and bastnasite. The oxide is obtained as an intermediate in the recovery of neodymium metal (See Neodymium).The oxide also may be formed by thermal dissociation of neodymium oxalate, hydroxide or carbonate:Nd2(C2O4)3 → Nd2O3 + 6CO22Nd(OH)3 → Nd2O3 + 3H2ONd2(CO3)3 → Nd2O3 + 3CO2.
合成方法混合希土類溶液から溶媒抽出法で分離したネオジム溶液をシュウ酸で沈殿させ，焙焼して酸化ネオジムとする
純化方法Dissolve it in HClO4, precipitate it as the oxalate with doubly recrystallised oxalic acid, wash it free of soluble impurities, dry it at room temperature and ignite it in a platinum crucible at higher than 850o in a stream of oxygen. It is a blue powder. [Tobias & Garrett J Am Chem Soc 80 3532 1958.]
