Abstract
A high-temperature superconductor of HgBa2Ca2Cu3O9-x with T c>130 K was prepared by the high-pressure technique. The lattice constants of a=3.852 Å and c=15.822 Å were determined by X-ray powder diffraction measurement, which were somewhat smaller than previously reported values. The T c value of the annealed sample was 130.3 K.Keywords
