Superconducting wire (Bi-2223)

Superconducting tape (Bi-2223) with silver layer at both ends for easy soldering of current and voltage wires. Suitable as a sample for measuring critical temperature, recommended measuring current up to 60 mA. The critical current at 77 K is a few tens of amperes (about 30 A at zero external magnetic field and about 10 A under a magnetic field of 25 mT). Critical temperature (midpoint): 110 K, Critical temperature (zero resistance): 108 K. Resistivity at room temperature: 1 milliohm.cm
