ABSTRACT:
A method for the synthesis of an oxide high-temperature superconductor of defined composition by sintering of the starting oxides, wherein sintering is effected in a chemically and phyically closed system by generating a preset oxygen partial pressure through the use of peroxide additives, and the oxidic starting mixture is chemically shielded against the container material and stabilized thermodynamically.
