제조 방법 · 1건

생산 방법Neodymium 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.
