Scope: This standard specifies the determination method of lanthanum oxide, cerium oxide, praseodymium oxide, neodymium oxide, samarium oxide, gadolinium oxide, terbium oxide, dysprosium oxide, holmium oxide, bait oxide, thulium oxide, ytterbium oxide and lutetium oxide content in yttrium europium oxide . This standard applies to yttrium and europium oxide (4.00%-8.00% europium oxide), lanthanum oxide, cerium oxide, praseodymium oxide, neodymium oxide, samarium oxide, gadolinium oxide, terbium oxide, dysprosium oxide, holmium oxide, bait oxide, thulium oxide, Determination of ytterbium oxide and lutetium oxide content. The measurement range is shown in Table 1. Table 1: Measurement range of oxides, % Lanthanum oxide 0.0001～0.010 Dysprosium oxide 0.0002～0.010 Cerium oxide 0.0005～0.010 Holmium oxide 0.0001～0.010 Praseodymium oxide 0.0005～0.010 Erbium oxide 0.0001～0.010 Neodymium oxide 0.0003～O.010 Thulium oxide 0.0001～0.010 0001～ 0.010 Samarium oxide 0.0005～0.010 Ytterbium oxide 0.0001～0.010 Gadolinium oxide 0.0002～0.010 Lutetium oxide 0.0001～0.010 Terbium oxide 0.0005～0.010
