Abstract :
Critical properties and structural features have been studied using composite tape silver sheathed Bi-2223 base superconductors manufactured by “powder in tube” method from precursors containing phase Bi-2212 in the range of 0-90%. The critical current densities of 4×104 A/cm2 (77 K, 0 T) and 1.3×105 A/cm2 (4.2 K, 5 T) have been realized in tape superconductors 0.18 mm×3.4 mm in section produced from a precursor containing 50% phase Bi-2212. A small pancake coil comprising 60 turns was processed by “wind and react” method using tape with optimized powder
