High temp superconductors (1 Viewer)

[kennalj]

ok ive got an assignment on superconductors and one dot point asks me to discuss advances that have led to higher temperature superconductors but i can't find any information on this topic anywhere. can anyone pls help?

Superconductors come in different critical temperatures right?

Notice the temperature scale is in Kelvin not Celsius.
T_K = T_C + 273.15

Mercury is a superconductor only at around 4.2K (-268.95^oC), and these temperatures require the more expensive liquid helium to cool them as opposed to the ceramic conductors which require the much cheaper liquid nitrogen (as cheap as beer) to cool them because their critical temperature is around 130K (around -136^oC).

Search for any superconductors, typically the ceramic ones with a critical temperature of around the 130K mark.
