Scope
This standard specifies the determination method for lanthanum oxide, cerium oxide, praseodymium oxide, neodymium oxide, samarium oxide, europium oxide, gadolinium oxide, dysprosium oxide, holmium oxide, erbium oxide and yttrium oxide content in terbium oxide. This standard is applicable to the simultaneous determination of lanthanum oxide, cerium oxide, praseodymium oxide, neodymium oxide, samarium oxide, europium oxide, gadolinium oxide, dysprosium oxide, holmium oxide, erbium oxide and yttrium oxide in terbium oxide (99%-99.95%). . The measurement range is shown in Table 1.
