Introduction:

There are 27 pure metals and more than a thousand different alloys, intermetallic compounds and some dielectric materials that can transition to a superconducting state

Superconductors

As mentioned earlier, materials that have the ability to transform into a superconductor when cooled to a very low temperature is called superconductors

Superconducting ring

The feature of superconductors is that the electric current created in a superconducting circuit will circulate for a long time along this circuit without reducing its strength.

Critical temperature

Known superconductors have very low critical transition temperatures and devices that use superconductors must operate under expensive liquid helium cooling.

Using of superconductors

Known superconductors have very low critical transition temperatures and devices that use superconductors must operate under liquid helium cooling.

Cryoconductors

Metals that can reach a small value of electrical resistivity at cryogenic temperatures are called cryoconductors.

Pure metal

To achieve high values of cryoconductivity, high purity and absence of defects in the crystal lattice of the metal are necessary.

Cheap coolers

If liquid helium is used as a cooling agent in superconducting devices, in cryoconductors devices cheaper refrigerants - liquid hydrogen or even liquid nitrogen.
