Superconductors with a critical temperature at room temperature.

    Has any scientist got close to finding a superconductor that has a critical temperature at room temperature?

    In my text book, the critical temperature of superconductors seems to get higher for more advanced alloys. Simple elements seem to have a lower critical temperature. Is there a pattern here?

    What do you think?

    Not yet afaik, it appears to be just a matter of time though - there is no known reason why there would be a maximum temperature at which a material can be in a superconducting state.

    There are Type 1 superconductors - mostly elemental metals - that are conductors at room temperatures and become superconductors at extremely low temperatures, and Type 2 superconductors which are compounds / alloys of different types - including some ceramics which are insulators at room temperature but become superconductors at relatively high temperatures.

    The mechanism of superconduction is completely different to normal conduction, and has more to do with the molecular structure than the properties of constituent elements.
