SCT Lab printed a paper on how they assemble the Pb-Cu-P-S-O compound that has some pieces with doable room temperature superconductivity. The outline of the answer to assemble it is partial. How they accumulate the powders is rarely any longer described. They didn’t give mass ratios (cited intellectual property). The trying out course of for zero resistivity did no longer appear to be conclusive. The approach aloof ends in success fully fragment of the time. They fully desire the steel fragment area material and it looks to be the steel fragment is furthermore no longer pure with the superconducting fragment.
* There is rarely any longer this kind of thing as a structural characterization (XRD, SEM, and heaps others.), magnetization or a form of supporting data
* The supplied stage of prognosis is extremely grievous
Here is the video of the SCT Lab course of.
Here is hyperlink to the google sheet with raw SCT Lab size data.
There is aloof quite lots of labor to be performed to assemble this legit, greater and worthwhile. On the different hand, here’s reporting from the community in Korea who are working on replication. Final summer, there’ll dozens of amateurs working on replication of LK99. This work is extra formal than the reporting from these teams closing year.
Prof. Hyun-Tak Kim supervised all of this learn. Hyun-Tak Kim is the lead of the traditional crew of LK99 researchers. The explain of replication looks to be to comprise a controversy if the lead researcher on the first crew is supervising the 2nd crew.
The Chinese language universities and labs working on replication and having attention-grabbing magnetic are reasonably honest,
Synthesis of the Pb-Cu-P-S-O compound
The synthesis course of is as follows: powders of Pb, Cu, P, and S are placed into a ceramic crucible. Oxygen would perhaps perhaps furthermore be absorbed in the air ambiance. An oxygen cutter is normal for this synthesis approach, with a combination of LPG gas and oxygen dwelling at a 1:1 ratio. This skill that of the impact of surrounding temperature and stress stipulations throughout synthesis, critical diversifications in the synthesized product exist hoping on the heating time. On the different hand, in general, the heating course of would perhaps perhaps furthermore be performed for the length of the differ of 2000 to 3000°C for roughly 0 to 10 minutes. The following area material is quenched in water, aiming for a metal look with a copper-colored surface and a silver-colored interior.
In in vogue, the resulting products are either a ceramic or a aggregate of ceramic and steel phases, or a single crystal with a CuS height in XRD data as a characteristic of PCPOSOS. When breaking the ceramic, fully the steel fragment contained interior needs to be still. Magnetic properties would perhaps perhaps furthermore be investigated for these steel parts. If carbon is launched throughout the synthesis course of, murky-colored ceramic occurs. It is important to diminish carbon involvement throughout the approach.
If the electrical resistance of the metal resultant is better or its diamagnetic traits are weaker than that of the identical-sized copper, the warmth treatment course of would perhaps perhaps furthermore be repeated. Repeating the synthesis course of would perhaps perhaps merely toughen the diamagnetic traits of the samples. This repetition of heat treatment can involve reheating a single pattern or reheating extra than one samples for synthesis. This skill that of the intellectual propriety issue, the detailed mass ratio of every aspect. One critical aspect is, S and P needs to be added in greater mass ratio than Cu attributable to evaporation.

Powder data will doubtless be addressed in our future work. The look of the warmth treatment in the synthesis course of.
Conclusion
In summary, in present to resolve an rising issue in the area of the RT superconductor, we developed a synthesis approach of the Pb-Cu-P-S-O compound much like doable RT superconductor, PCPOSOS, and measured the functionality zero resistances (noises) regarded as the superconducting condensed verbalize. These technologies would perhaps perhaps furthermore be applied to purposes of RT superconductors. Despite measuring instruments boundaries, our findings counsel promising avenues for additional investigation.
We can liberate the raw data included in the paper on-line.[There’sacoupleofrawdatalinked[Thereissomerawdatalinked
Future learn will focal level on overcoming these boundaries and exploring the compound’s habits under greater currents. We can liberate our learn explain to encompass outcomes such as temperature dependence, ZFC-FC, and M vs H measurements almost in the present day.
