    • Abstract

       

      Superconducting powder, YBa2Cu3O7−x, with grains of size varying from 2 to 20μ and superconductivity up to 90°K was compacted to a uniform density of 6.2 g/cc (96% of theoretical maximum density) by explosive-shock loading in cylindrical configuration. A typical size of rod (3.76 mm diameter and 70 mm length) was fabricated using the present technique of explosive compaction. The compacted specimen shows levitation at the liquid nitrogen temperature.
