None of this is peer reviewed yet, to my knowledge so caveat emptor. However, it's extremely interesting.

This synthesis method is so simple that it can be reproduced in a high school laboratory. The most important thing is that the paper also verified that the superconducting resistance is zero and the Meissner effect. If the paper is true, it is really outrageous. Synthesis in three steps:

Step 1: Synthesis of Chaloste Pb2(SO4)O Mix lead oxide PbO and lead sulfate Pb(SO4) powders in a crucible at a ratio of 50% each, heat the mixed powder in a furnace at 725 degrees for 24 hours in the presence of air, and the mixture undergoes a chemical reaction. Generates chalkite.

Step 2: Synthesis of Cu3P Cu3P Copper Cu and phosphorus P powders were mixed in a crucible according to the ratio, and the mixed powder was sealed in a 20 cm per gram sealed tube with a vacuum degree of 10-3 torr. The sealed tube was heated in a furnace at 550°C for 48 hours to eventually produce cuprous phosphide crystals.

Step 3: To generate room temperature and pressure superconductor Pb(10-x)Cux(PO4)6O Grind chalcopyrite and cuprous phosphide crystals into powder and mix them in a crucible, then put them into a sealed tube with a vacuum of 10 torr. Heat the sealed tube in a furnace at 925°C for 5-20 hours, and finally generate a copper-doped lead apatite Pb(10-x)Cux(PO4)6O, which is a superconducting material at room temperature and pressure.
