The platelet bulk specimen Bi2Sr2CaCu 2Oy sandwiched between Ag disks was shocked to 5 GPa using shock loading method. The shocked specimen showed high orientation to c-axis and consolidation of high density of 95 %. Ag particles of about 10 nm were observed on the surface of Bi2Sr2CaCu2O y specimen by TEM. The magnetization of zero field cooling strongly increased and Tc reached to 8 4 K from 74 K by the annealing at 650°C for 12 hs in N2 after shock loading. The ΔM (the difference of FC and ZFC) was enhanced about 50 times than pristine specimen. The introduction of pinning site was discussed in connection with jetting effects of shock wave.
