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),
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.
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.
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 ...
A piece of cuprate of bismuth and strontium: this piece is a cube with an edge of nearly 1 mm. Bismuth strontium calcium copper oxide (BSCCO, pronounced bisko), is a type of cuprate superconductor having the generalized chemical formula Bi 2 Sr 2 Ca n−1 Cu n O 2n+4+x, with n = 2 being the most commonly studied compound (though n = 1 and n = 3 have also received significant attention).
A room-temperature superconductor is a hypothetical material capable of displaying superconductivity above 0 °C (273 K; 32 °F), operating temperatures which are commonly encountered in everyday settings.
Breakthrough would mark ‘holy grails of modern physics, unlocking major new developments in energy, transportation, healthcare, and communications’ – but it is a long way from being proven
An organic superconductor is a synthetic organic compound that exhibits superconductivity at low temperatures. As of 2007 the highest achieved critical temperature for an organic superconductor at standard pressure is 33 K (−240 °C; −400 °F), observed in the alkali-doped fullerene RbCs 2 C 60. [1] [2]
