| titleOfInvention | Rare earth oxide standard sample and preparation method thereof |
| abstract | The invention relates to the technical field of standard sample preparation, in particular to a rare earth oxide standard sample and a preparation method thereof. The rare earth oxide standard sample in the present invention includes a homogeneous mixture of rare earth oxide and sodium chloride; in terms of mass percentage, the rare earth oxide in the rare earth oxide standard sample is 28% to 42%, and the rare earth oxide includes Lanthanum oxide, cerium oxide, praseodymium oxide and neodymium oxide; the lanthanum oxide is 0.1% to 15%, the cerium oxide is 0.2% to 28%, the praseodymium oxide is 0.1% to 8%, and the neodymium oxide is 0.5%~32%. By using sodium chloride as a diluent, the total rare earth concentration can be effectively reduced, and the content range of the standard value can be accurately controlled to ensure that the standard value of the standard sample is consistent with the total rare earth content of the actual product (rare earth carbonate and rare earth chloride), and further accurate Control product quality; and standard samples have high uniformity and stability. |
