The LK99 Superconductor

The latest advance boils down to something that's called LK99. It's a modified lead appetite, which is essentially a compound made of lead copper, phosphorus, and oxygen. And once this ingot is created, it's said to become a superconductor at 400 K. The researchers say in their paper, all evidence and explanation lead that LK99 is the first room temperature and ambient pressure superconductor.
