- Аннотация: YBa2Cu4O8 single phase bulk superconducting ceramics was successfully synthesized using the new suggested method of hot pressing (HP) at 750-degrees-C and 500 kg/cm2 in air atmosphere during 25-50 h from a precursor mixture, consisting of Y2O3, Ba2Cu3O5 and CuO, obtained by spray drying and thermodecomposition of nitrate solution. Our method allows one to combine in one stage the synthesis of pure phase YBa2Cu4O8 with the production of bulk superconducting ceramics with a stable and reproducible T(c) = 82-78 K. The cell parameters with estimated standard deviations were calculated from XRD data: a = 3.841(1) angstrom, b = 3.879(1) angstrom and c = 27.258(6) angstrom. AC susceptibility measurements were carried out. Transport current density measurements on bulk samples are in progress now. The method can be used in the large scale production of HTSC-ceramics YBa2Cu4O8.
