In the context of research on new materials for next generation nuclear reactors, it becomes more and more interesting to know what can be the advantages of nano-structured materials for such applications. In this study, we performed irradiation experiments on micro-structured and nano-structured {beta}-SiC samples, with 95 MeV Xe and 4 MeV Au ions. The structure of the samples was characterized before and after irradiation by grazing incidence X-ray diffraction and Raman spectroscopy. The results showed the occurrence of a synergy between electronic and nuclear energy loss in both samples with 95 MeV Xe ions, while the nano-structured pellet was found to have a better resistance to the irradiation with 4 MeV Au ions.
