Аннотация:
The preparation of textured single and multifilamentary wires and tapes of the 110 K phase Si(Pb)-2223 by the powder-in-tube method using a silver sheath is reported. High critical current densities (8000 A/cm<sup>2</sup> at 77 K and 0 T) have been obtained by means of a repeated rolling and sintering process. The J<sub>c</sub> magnetic field dependence at 77 R up to 2000 Oe has been studied.
