In the present work, Bi2Sr2CaCu2O 8 (Bi-2212)/MgO compound was prepared using the conventional solid-state reaction method. The powder of nanosize MgO particles was added to Bi-2212 superconductor with weight percentage of 3%, 5%, and 8%, respectively. The compound was sintered for 48 hours at 855de...
