Conventional superconductor


Conventional superconductor

Conventional superconductors are materials that display superconductivity as described by BCS theory or its extensions.(cf. Unconventional superconductor)

Critical temperatures of some simple metals:

Element Tc (K)
Al 1.20
Hg 4.15
Mo 0.92
Nb 9.26
Pb 7.19
Ta 4.48
Ti 0.39
V 5.30
Zn 0.88

Niobium and vanadium are type-II superconductors, while most other superconducting elements are type-I materials. Almost all compound and alloy superconductors are type-II materials.

The most commonly used conventional superconductor in applications is a niobium-titanium alloy - this is a type-II superconductor with a Tc of 11 K.

The highest critical temperature so far achieved in a conventional superconductor was 39 K (-234 °C) in magnesium diboride.
