Comparative change in the structure of superconductive Bi – 4457 and (Bi – Pb) – 4457 ceramics through explosive compaction

We conducted comparative research into superconductive Bi – 4457 and (Bi – Pb) – 4457 compacted ceramics. We noted that the addition of lead exerted a destabilizing effect on superconductivity and the correlation between restructuring of the crystal lattice and the superconductivity properties occurring with a change in the detonation pressure.
