The feasibility of manufacturing high Tc-superconductor wires on the basis of YBaCuO-123 had to be evaluated. Powder-pressed specimens of YBaCuO-123 were encapsulated in copper tubes (precursors) and shaped to wires by means of HIP and wire drawing. A barrier system against O_2-loss as well as the addition of Ag_2O acting as O_2-donator had been provided in this precursors. Fine-dispersed Ag was added to the high Tc-powder as ductilization component. Furthermore, the feasibility an orientation of the superconductor phase in direction of the wire axis corresponding with the best current bearing capacity of the sc phase was investigated. Since the technological aspects of this investigation (wire, drawing, geometrical reduction of the precurs...
