Korean Team's LK99 Room Temperature Superconductor

Wednesday - September 13 2023, 08:06 UTC - 1 year ago

Hyun Tak Kim and other members of the original korean LK99 room temperature superconducting team should have an American Institute of Physics Materials paper published in a few weeks. They are trying to prove the superconductance of the thin film LK99 material. The description and proof requires far more detail with currently the resistivity of LK-99 being 1/10,000 to 1/100,000 of copper. Their results show superconductive properties with the superconductor consisting of lead apatite of phases with three different critical temperatures. There is also lead compounds (40%) and Copper compounds (10%) as well as some Silicon added in the process. The dopants and defects needed for the material to be a superconductor are detailed with Scanning Electron Microscope pictures of all the important phases in both methods.

Hyun Tak Kim and other members of the original korean LK99 room temperature superconducting team should have an American Institute of Physics Materials journal paper published in about 3 to 5 weeks. They submitted a version and have been asked to make revisions.

The key information that I would like to see is verified or verifiable proof of the superconductance of the thin film LK99 material.

Q-center Patent on Thin Film Superconductance .

* More description of the vapor deposition process that makes the micron(s) thick thin film which is the only material claimed to be superconducting .

* They claim they get 48.9% of the lead apatite thin film as superconductive.

The description and proof on the thin film requires far more detail in any new paper from Hyun-Tak Kim.In the patent, they show and state there is superconducting levels of low resistance. The resistivity of LK-99 was 1/10,000 to 1/100,000 of copper.

For Example 4, the grains of the solid phase reaction were processed into a square shape and the resistance change according to the temperature change (304K ~ 382K) was measured using equipment (Power (voltage/current) Source KEITHLEY 228A, Sensitive Digital Voltmeter KEITHLEY 182, Probe Method: Measured using the 4-probe method) and the results are shown in FIG. 29. Referring to this, it can be seen that the ceramic compound according to the present invention exhibits superconductive properties.

In addition, FIG. 42 is a photograph of an experiment in which resistance was measured in real time for Example 4, and the measured resistance was approximately 10^-12 Ohms per centimeter. Very low resistance in Ohmcm.Thanks to twitter user @8teAPi for the info on the patent info.

Solid State Synthesis .

– They've described this before, but now include a little Silicon in the mixture. But they don’t say how the Si got in there! .

– They claim they get 48.9% lead apatite which is superconductive, with two other lead compounds (40%) and Copper compounds (10%).

– However lead apatite itself is an insulator, they say they need doping and defects to make it into a superconductor.
