| Popis: |
High-Jc silver-sheathed BiPbSrCaCuO superconducting wires were fabricated through the solid reaction method. These wires showed the maximum Jc of 2.5X 104 A/cm2 (77. 3K) in a zero magnetic field and 1.2X104 A/cm2 at 0.1 Tesla. Key factors for high-Jc wires are: dominant high-Tc phase, highly oriented structures, good bonding at grain boundaries and fine dispersion of non- superconducting phases. When the wire was immersed in liquid helium, maximum Jc of 3.8X104 A/cm2 at 23 Tesla was achieved. 50cm length conductors were fabricated. These conductors were tested and proved to have Ic of practical levels; 170 A at 77.3K and 1000 A at 4.2K. These results show the promising potential of silver-sheathed BiPbSrCaCuO superconducting wires. |
