Increasing Number of Fake LK99 Levitation Videos

by

There are real LK99 Videos and there is an increasing number of fake LK99 room temperature superconductor videos.

There are pure video effect fakes and those using strings or wires.

However, there are real videos of flakes and pieces with partial levitation.

The complete levitation video from China had reportedly been claimed to be fake.

  1. So real question here. What would happen of you ground the LK99 sample into dust. Assuming it is heterogenous this should separate the less pure and more pure bits. Then use the magnet to sperate. Any real superconductor should Flux pin and hover. Impurities won’t?

    • Depends on what scale the structures exist that would give rise to the superconductivity. Grind it too small, and you destroy the effect. It’s sintered powder to begin with, so you could reasonably expect the effect to only really be contributed to by grain boundaries with minor diffusion either side. Maybe the diffuse region is the part with the superconducting properties, maybe it’s the boundary itself. Grinding up the sample would be a good test, if you could control the grain sizes and perform multiple tests on multiple samples. Grind it smaller than the original powder, and you could either rule out or confirm the diffuse region being the superconducting region. If that is the case, the impurities could be reduced by starting with a finer particulate.
