Abstract
The high pressure-high temperature (HP-HT) synthesis of the Hg-1201 and Hg- 1223 superconducting cuprates was analysed by real-time, in-situ synchrotro n diffraction. The main parameter controling the synthesis is the temperatu re which in turn strongly depends on pressure. The formation of Hg-1223 inv olves the apparition of Hg-1212, which then reacts with Ca2CuO3 and CuO to yield Hg-1223.
