Scope
This standard specifies the determination method for the content of lanthanum oxide, cerium oxide, praseodymium oxide, samarium oxide and yttrium oxide in metallic neodymium and neodymium oxide. This standard applies to the simultaneous determination of lanthanum oxide, cerium oxide, praseodymium oxide, samarium oxide and yttrium oxide in metallic neodymium and neodymium oxide (99% to 99.9%). The measurement range is shown in Table 1.
