Lee, Kim, et al. reported in July 2023 that a modified lead apatite material, Pb10-xCux(PO4)6O (0.9 < x < 1.1), exhibited superconductivity at room temperature and atmospheric pressure [1, 2]. However, their X-ray diffraction data clearly showed the presence of impurity phases, including Cu2S, raising uncertainty about the sample quality. Subsequent studies have been conducted; however, different samples exhibited various physical properties. To verify the recipe for the sample growth process, we synthesized samples following the methodology outlined in the reference [1, 2]. An analysis of the structure and physical properties of the synthesized sample reaffirms the critical importance of high-quality sample growth.
