Abstract

Abstract

The well-known oxide superconductors were treated or sintered under high pressure and high temperature. It is found that the Tc of superconductors of SrLa(CuAg)1Ox sintered at ambient had been increased from 20 K to 28 K after some heat treatment under high pressure. However the Tc has not been increased in oxide sample of Y1Ba2Cu3O7- for both samples high pressure-sintered and heat treated under high pressure, the latter was pre-sintered in air. Nevertheless, these samples sintered at 2.0 GPa have higher microhardness and density, and their lattice parameters were changed.
