- LK-99 – a copper, lead, phosphorus, and oxygen compound
- Synthesized by a Korean team at a start-up firm.
- Quantum Energy Research Centre, Seol
- Led by Sukbae Lee and Ji-Hoon Kim
- LK – surnames + 1999 (when LK-99 was first synthesized)
- Superconductor at room temperature and above as high as 127 °C
- Superconductor at ambient pressure
- Samples show zero electrical resistance.
- Samples show Meissner Effect
- Meissner Effect – means zero magnetic field inside a superconductor.
- Meissner Effect – when a material expels a magnet – thus levitates above it.
- “Electricity flow at room temperatures with zero resistance”
The condition so far
- No superconductor material at ambient conditions so far
- Some synthesized materials have shown superconductivity.
- But only under extremely low temperatures or high pressures
No other ‘replicative’ studies supported it so far.
- Studies replicated LK-99 synthesis.
- No superconductivity found at ambient conditions.

- Experts – data by the Korean team is not convincing
