All the samples were prepared using the conventional solid-state reaction method. For samples to be irradiated with electron particles, 5% weight percentage of nanosized MgO was added to absorb certain amount of the energy from electrons and thus reducing the formation of complicated defects structure in the Bi-2212 superconductor. The SEM micrographs of the Bi-2212 superconductor showed the existence of platelet-type grains of Bi-2212 phase in both non-irradiated and irradiated samples. The XRD patterns for the non-irradiated and irradiated samples showed well-defined peaks of which could be indexed on the basis of a Bi-2212 phase structure. The phase purity, lattice parameter, surface morphology and degree of crystallinity for the non-irradiated and irradiated samples were also compared and analyzed and it was found that both the gamma and electron irradiation have considerable effect on the mechanical properties of Bi-2212 superconductor. When subjected to gamma and electron irradiation, the microstructure of the samples was found to be more textured and consequently enhanced the strength of the samples. � 2017 Trans Tech Publications, Switzerland.
