In this study, we first investigated the detailed crystal structures of four natural apatite by single crystal X-ray diffraction (SXRD) combined with a scanning electron microscope (SEM) equipped with energy dispersive X-ray spectroscopy (EDX) measurement. Secondly, pilot experiments of doping copper (Cu) atoms into the apatite lattice were carried out by high-temperature mixed pure copper and natural apatite powders. Finally, copper-doped lead apatite has been synthesized via a three-step solid-state reaction method, and its crystal structure has been determined using SXRD, SEM/EDX, and transmission electron microscopy (TEM).","abstract_license":"CC-BY (publisher license, via OpenAlex)","license":"cc-by","is_open_access":true,"retracted":false,"peer_reviewed":null,"categories":["Crystal Structures and Properties"],"details":null,"provenance":"openalex","attribution":"Abstract of \"The Crystal Structure of Apatite and Copper-Doped Apatite\" by Yibo Liu, Changzeng Fan, Bing Zhang et al., https://doi.org/10.70322/gct.2025.10005, used under its Creative Commons Attribution license (CC-BY); markup removed, otherwise unmodified.","topics":[{"slug":"room-temperature-claims","name":"Room-Temperature Superconductivity Claims & Replication","domain_slug":"superconductivity"}],"cited_in_dossiers":[]}
