Is the Earth's core a potential high-temperature superconductor?

Click For Summary
SUMMARY

The discussion centers on the potential of the Earth's core being a high-temperature superconductor, referencing research from Argonne National Laboratory regarding nickel compounds. Participants clarify that while certain materials can exhibit superconductivity under high pressure, the extreme temperatures of the Earth's core negate this possibility. Specifically, compounds like LaH10 have been identified as superconductors under pressure, but the core's high temperature prevents superconductivity from occurring naturally. The conversation emphasizes the distinction between theoretical possibilities and practical realities in superconductivity.

PREREQUISITES
  • Understanding of superconductivity principles and mechanisms
  • Familiarity with high-pressure physics and its effects on materials
  • Knowledge of specific superconducting materials, such as MgB2 and LaH10
  • Awareness of the Earth's geological structure, particularly the core composition
NEXT STEPS
  • Research the properties and applications of LaH10 as a superconductor under high pressure
  • Explore the effects of temperature and pressure on superconductivity in various materials
  • Investigate the geological composition of the Earth's core and its implications for superconductivity
  • Study the advancements in high-temperature superconductors and their potential applications
USEFUL FOR

Geophysicists, materials scientists, and researchers interested in superconductivity and its applications in extreme environments.

No, not really.
There are perhaps compounds in the core that would superconduct if you cooled them to a low enough temperature; but the temperature a the core is high not low.

Note that there are LOTS of materials that can superconduct; (nearly) all the metals in the periodic system can be made to superconduct at low enough temperatures and/or high enough pressure. There are also lots of superconducting compounds.
Some, like MgB2 , had been in use for many, many years before someone realized that they became superconducting at relatively high temperatures

Hello to all

Can we consider the core of the Earth to be a superconductor ,for example Aragon national laboratory hinted for some thing like that
https://www.anl.gov/article/nickel-...tential-for-hightemperature-superconductivity

That been said , what test could verify or disprove this idea

First of all, it is "Argonne", not "Aragon. I used to work there, so I'm "sensitive" about someone mangling the name.

Secondly, it is well-known that one can get elevated transition temperatures at high pressures for several superconductors. So this isn't new. However, to say that the hot, heated core of our Earth is a superconductor simply due to the high pressure is a stretch by any imagination. As has been stated, the core is at such a high temperature, it would melt if it were not under pressure.

Zz.

Sorry for the mistake in the name

Pressurised superconductors are achieved for LaH10

Dose NiFe able to become a superconductors under high pressure.
 
And another question the core is solid metal ?
