Document Type and Number:
WIPO Patent Application WO/2023/027537
Kind Code:
A1
Abstract:
A room-temperature and atmospheric-pressure superconducting ceramic compound and a preparation method therefor are disclosed. The room-temperature and atmospheric-pressure superconducting ceramic compound and the preparation method therefor, according to the present invention, comprise a ceramic compound of chemical formula 1, A10-xBx(PO4)6O (A is Ca, Ba, Sr, Sn or Pb, B is Cu, Cd, Zn, Mn, Fe, Ni or Ag, and x is 0.1-2.0), and the superconducting ceramic compound exhibits superconducting properties at room temperature and at atmospheric pressure.
