锆石（ZrSiO4）具有可以结合锕系元素的结构。因此，通过加速辐照实验研究了锆石结构对辐照损伤的敏感性。合成 Zr1xNdxSiO4x/2 (x 1/4 0, 0.01, 0.10) 陶瓷在室温下用 0.5 MeV 4He2+ 离子（注量 1 1014e1 1017 离子/cm2）进行辐照。研究了辐照对陶瓷的相结构和化学稳定性的影响。研究发现，主要晶体结构得以保留，但由于强化照射，几乎没有导致非晶化。拉曼光谱显示，随着注量的增加，主峰稍微变宽和减弱，表明辐照几乎没有引起非晶化。随着钕含量的增加，耐辐照性得到增强。此外，即使在辐照后，微形貌和元素分布也没有改变。尽管 LRNd 随着 Nd 负载和辐照的增加而略有增加，但仍保持了优异的化学稳定性（~104 g m2 d1）。
Zircon, ZrSiO4, has a structure that can incorporate actinides. Therefore, the susceptibility of the zircon structure to irradiation damage has been investigated by accelerated irradiation experiments. Synthetic Zr1xNdxSiO4x/2 (x ¼ 0, 0.01, 0.10) ceramics were irradiated with 0.5 MeV 4He2þ ions (fluences 1 1014e1 1017 ions/cm2) at room temperature. The irradiation effects on phase structure and chemical stability of the ceramics were investigated. It is found that the main crystal structure is maintained, however, little amorphization is leaded as a result of intensified irradiation. Raman spectra reveal that the main peaks slightly broaden and weakened with increasing fluence, indicating little amorphization has been induced by irradiation. The irradiation resistance is enhanced by the growing neodymium content. Moreover, microtopography and element distribution have no changed even after irradiation. Although the LRNd increases slightly with increasing Nd loading and irradiation, the excellent chemical stability (~104 g m2 d1) is maintained.
