Abstract

In this paper, the effect of shock compression on the synthesis of a Bi-based oxide superconductor was investigated. Bi1.85-Pb0.35-Sr1.90-Ca2.05-Cu3.05-Ox calcined powder was shock-compacted around 20 GPa and 30 GPa, and divided specimens were annealed at 845 °C for 1, 6 and 48 hours. The specimens were evaluated by x-ray diffraction and scanning electron microscope.
