The Materials Science of Modern Technical Superconducting Materials
One feature of these materials is the formation of a superconducting compound inside the finished wire in the course of diffusion heat treatment. Nb 3 Sn-based superconductors are fabricated using the "bronze" method, the internal tin source method, and "powder in a tube" (PIT) [18–22].].
