Superconducting bulk was made from shock compacted materials with annealing 72 hours at 845 degrees Celsius in the air. Super conducting bulk was atomized and included into a starting material as seed crystals, then shock compacted at 10 to 30 GPa and annealed again expecting becoming higher quality. A whisker was observed from the sample that is including seed crystals 30%, shock compacted at 20 GPa and annealed for 72 hours.
