Korean team claims to have created the first 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 computers, magnetic levitation trains, and powerful medical devices. However, most superconductors only work at very low temperatures, which require expensive and complex cooling systems.

How did the Korean team create their superconductor?

According to two papers posted on the arXiv preprint server, the Korean team created a new material called LK-99, which is a mixture of lanarkite (Pb2SO5) and copper phosphide (Cu3P). They claim that this material becomes superconducting at room temperature and normal pressure, which is a breakthrough in physics. They say they used a solid-state reaction method, which involves heating and compressing the mixture in a sealed vacuum tube.

How did the Korean team test their superconductor?

The Korean team says they measured the electrical resistance and magnetic properties of LK-99 and found that it shows zero resistance and the Meissner effect, which are the hallmarks of superconductivity. The Meissner effect means that a superconductor expels magnetic fields and can levitate above a magnet. The team has provided a video of the material partially levitating, which they say is due to impurities in their sample.

How reliable are the Korean team’s claims?

The Korean team’s claims have not been peer-reviewed or replicated by other researchers, which is the standard process for verifying scientific discoveries. There have been previous false claims of room-temperature superconductors, such as in 1989, when two chemists announced they had achieved cold fusion, but later retracted their results. Therefore, many experts are skeptical and cautious about the Korean team’s claims, and say they need more evidence and independent verification.

What are the implications and challenges of the Korean team’s claims?

If the Korean team’s claims are true, LK-99 would be a revolutionary discovery that would transform the fields of electricity and electronics, and open up new possibilities for innovation and development. However, there are also many challenges and questions that need to be addressed, such as:

  • How stable and reproducible is LK-99, and can it be scaled up and mass-produced?
  • How does LK-99 achieve superconductivity, and what is the underlying mechanism and theory behind it?
  • How can LK-99 be integrated and applied to existing and future technologies, and what are the potential benefits and risks?

The Korean team says they are working on answering these questions and improving their material, but they also urge the international community to join them in exploring this new frontier of physics.
