Shock compaction experiments are performed in vacuum for Nd-system superconductor particles (NdBa2Cu3O7-x) which has a peak effect in the high magnetic field region of near 2T. The as-shocked specimen shows an c-axis oriented crystal structures with the lattice constant of the orthorhombic cell:a=0.5787nm, b=0.5874 and c=1.17462nm calculated by XRD(X-ray powder diffraction method)-analysis just after the shock compaction under 5.7Gpa. From SEM(scanning electron microscopy)- and AFM (atomic force microscopy)-observations, the surface of the specimen for as-shocked Nd-system has larger grains of 4-10 micrometer in length with growth steps caused mainly frictions among the particles in shock compaction.
