About superconductivity


Such superconductors are called “a powder in a pipe” because superconductive material is located in a cannel of very small diameter in a conductor. Even in the middle of 90s of the XXth century production of such superconductors in considerable quantities began, i.e. the technology had been already mastered. The largest producer of such superconductors is Japanese company SUMITOMO. However as 2/3 of such superconductors is silver, a very expensive metal, their application appears more and more problematic. Moreover such superconductor is attackable for magnetic fields created by other devices. This strongly limits their application even today saying nothing of future when science and engineering are developed.
