Korean physicists claim to have created room-temperature superconductor


What is a superconductor and why is it important?

A superconductor is a material that can conduct electricity without any resistance, meaning that no energy is lost as heat. This has many potential applications, such as faster and more efficient electronics, powerful magnets, and levitating trains. However, most superconductors only work at very low temperatures, which limits their practical use.

How did the Korean team create their superconductor?

According to two papers posted on the arXiv preprint server, the Korean team claims to have created a new material called LK-99, which has zero resistance at room temperature and normal pressure. They say they achieved this by mixing two compounds, lanarkite (Pb2SO5) and copper phosphide (Cu3P), and heating them in a sealed vacuum tube. The resulting material is a dark gray powder that can levitate above a magnet.

What evidence do they have for their claim?

The team says they have measured the electrical and magnetic properties of LK-99 and found that it shows the characteristics of superconductivity. They have also provided a video of the material partially levitating above a magnet, which they say is due to the Meissner effect. This is a phenomenon where a superconductor expels magnetic fields from its interior, creating a repulsive force.

How reliable are their results?

The team’s results have not been peer-reviewed or replicated by other researchers, so they should be treated with caution. There have been previous claims of room-temperature superconductors that turned out to be false or flawed. The team also acknowledges that their material has some impurities and defects that may affect its performance.

What are the implications of their discovery?

If the team’s claims are true, they would have made one of the biggest breakthroughs in physics history, as well as opening up new possibilities for technology and innovation. However, they also face many challenges and questions, such as how to scale up their production, how to explain their mechanism, and how to verify their results independently. The scientific community will be watching closely to see if LK-99 can live up to its promise.
