He then describes how bad the replication efforts have been and how poorly the Korean preprints described the process.
Nextbigfuture emphasizes that the disappointment and misjudgement was upon those who thought LK99 would be easy to replicate and that the description provided was sufficient.
2. A widely followed Twitter reported step by step effort at replication had some partial levitation. It was a tiny flake that was about one part per million of the original material.
3. The original reported measurements of the LK99 bulk material never reported superconducting resistance. The only measurement that the team had with superconducting low resistance was the thin film chemical vapor deposition material.
None of the teams who have published so far have attempted to make the chemical vapor deposition version of LK99. This is likely because the description for this process was even worse with temperature ranges from 500 to 1000 degrees.
That interpretation might gain some support from things like this, an updated Korean-language patent application. I neither read nor speak Korean, unfortunately, but I can see that figure on the first page, and it shows zero resistance kicking in at a temperature of just under 105 C.
