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