August 2, 20232 yr Even if the results are verified, what could be the next step? What has been made superconductive is a mineral, Lead Apatite. I assume one would have to process it into pure metal in order to make practical conductors like transformer windings, power transmission lines, etc. I don't think lead is suitable for that. Maybe the process can be made to work with other metal combinations but, maybe lead/copper is the only combination which works. Dugald Walker

August 3, 20232 yr Author IveI've heard it said that for higher amperage practical applications, some cooling would still be required. Easy cooling though, nothing like the extreme cooling required with previous superconductors. Edited August 3, 20232 yr by martin-w

August 8, 20232 yr It doesn't look good. The story so far: "The magnetization measurements on SQUID show that LK-99 is diamagnetic at 280K, and there is no sign of superconductivity in LK-99 at room temperature. The sample is highly resistive as well." https://arxiv.org/ftp/arxiv/papers/2308/2308.03544.pdf Also, "Beijing Superconductor Levitation Video Author Admits Fraud, Takes it Down" https://www.tomshardware.com/news/lk-99-video-fraud-taken-down Also, references to tweets from the Condensed Matter Theory Center show no superconductivity found in LK-99: https://www.iflscience.com/hopes-dashed-as-lk-99-confirmed-not-to-be-a-room-temperature-superconductor-70165 Dugald Walker
