• HGBA2CUO4+DELTA

The Hg-Ba-Ca-Cu-O system phase diagram and the formation of HgBa2Can-1CUnO2n+2+delta superconducting phases have been investigated by XRD (x-ray diffraction). The isothermal sections of the HgO-BaO-CuO system at 800 degrees C and the BaO-CaO-CuO system at 870 degrees C are presented, HgBa2Can-1CUnO2n+2+delta superconducting phases are formed through the reactions of HgO with intermediate products Ba2CuO3 + BaCuO2 + CaO, BaCuO2 + CaO2, and BaCuO2 + Ca2CuO3 for n = 1, 2, and 3 phases, respectively.
