Shock compaction experiments were carried out for Bi2Sr2CaCu2Oy partic
les sorted to 46-74 mu m and packing density of 50-82% at a shock pres
sure of 8 GPa. Bulk density reached 95% by shock compaction independen
t of the porosity. The most effective orientation was achieved by shoc
k loading for the packing density of 67% and with post annealing at 87
0 degrees C. The texture of the shocked plus postannealed specimen sho
wed crystal growth not only within the c-plane but also along the c-ax
is. The Meissner volume fraction of the shock compacted specimen decre
ased with decreasing packing density but the onset temperature did not
change. The magnetic torque of shock plus annealed specimen showed th
e alignment of particles.
