Notizen: Abstract High purity ceramics of the superconducting phases Hg1−xRexBa2Ca2Cu3O8 have been prepared by the vacuum sealed quartz tube techniques. The superconductors were obtained using precursor powders of Ba2Ca2Cu3Ox mixed with stoichiometric additions of ReO2 and HgO. The reaction was carried out in two steps: Firstly, the Ba2Ca2Cu3Ox was homogenised and annealed with ReO2 in oxygen atmosphere. Finally, the powders were mixed and pressed with stoichiometric additions of HgO and were encapsulated in an evacuated quartz tube and annealed at different rates and temperatures in order to optimise the purity of the phase.
