Low-temperature superconductor (LTS) wires are made from superconductors with low critical temperature, such as Nb 3 Sn (niobium–tin) and NbTi (niobium–titanium). Often the superconductor is in filament form in a copper or aluminium matrix which carries the current should the superconductor quench for any reason.
However, currently known high-temperature superconductors are brittle ceramics that are expensive to manufacture and not easily formed into wires or other useful shapes. [4] Therefore, the applications for HTS have been where it has some other intrinsic advantage, e.g. in: low thermal loss current leads for LTS devices (low thermal conductivity),
High-temperature superconductors (HTS) become superconducting at more easily obtainable liquid nitrogen temperatures, which is much more economical than liquid helium that is typically used in low-temperature superconductors. HTS are ceramics, and are fragile relative to conventional metal alloy superconductors such as niobium-titanium.
If a new superconductor works out, its 100% efficiency will make the worldwide grid even more of a no-brainer. Paul deLespinasse: Room temperature superconductors, the worldwide grid, solar energy ...
Room temperature superconductors will have immense consequences for a worldwide electrical grid allowing the whole planet to run on solar energy. Paul F. deLespinasse: Room temperature ...
Since the discovery of high-temperature superconductors ("high" being temperatures above 77 K (−196.2 °C; −321.1 °F), the boiling point of liquid nitrogen), several materials have been claimed, although not confirmed, to be room-temperature superconductors. [6]
The table below shows some of the parameters of common superconductors. X:Y means material X doped with element Y, T C is the highest reported transition temperature in kelvins and H C is a critical magnetic field in tesla. "BCS" means whether or not the superconductivity is explained within the BCS theory.
