对六家公司生产的高纯氧化钕进行了143 Nd/144 Nd同位素比值和稀土杂质的测定。试剂的同位素比分为四组，从0.511463到0.512238不等。某些试剂中镧、铈和钐的杂质含量超过1 ppm。根据结果制备钕同位素参考品。
143Nd/144Nd isotopic ratio and rare-earth impurities are examined for high purity neodymium oxide prepared by six chemical companies. The isotopic ratios of the reagents are grouped into four and vary from 0.511463 to 0.512238. Some of the reagents contain impurities more than 1 ppm for lanthanum, cerium and samarium. A neodymium isotopic reference will be prepared according to the result.
