Lead-substituted cuprous lead apatite as well as preparation method and application thereof

The invention discloses lead substituted cuprous lead apatite as well as a preparation method and application thereof, and belongs to the technical field of superconducting materials. The molecular formula of the lead substituted cuprous lead apatite is Pb8 + xCu2-x (PO4) 6, and x is greater than 0 and less than or equal to 2. The lead substituted cuprous lead apatite new material is obtained for the first time, and the lead substituted cuprous lead apatite material shows the superconductivity characteristic under the conditions of normal temperature and normal pressure and comprises a diamond-shaped MH loop with stable reproduction, stable and negative initial magnetic susceptibility of an original MH curve, stable low-field diamagnetism and high-field paramagnetism of an MT curve and the like. Therefore, the lead-substituted cuprous lead apatite room-temperature normal-pressure superconducting material has a better application prospect in the fields of energy power, medical health, transportation, basic sci
