Bi-2223 Magnetic Shields

Picture
Superconducting ceramic tubes and vessels with hemispherical bottom are suitable for perfect shielding of AC/DC magnetic field, e.g. in devices equipped by SQUIDs used in medicine, biomagnetism, nondestructive testing, physics etc. The shields may be supplied in custom made shapes.

Material: Bi1.8Pb0.26Sr2Ca2Cu3O10+x (2223 phase)
Density: > 5.0 g/cm3
Wall thickness: approx. 1.5 mm
Shielded magnetic flux density (77 K): > 5 mT (typical value 10 mT)
Shielding factor (77 K, amplitude 2 mT, frequency 20 Hz – 10 kHz): > 10^6
Shielding effectiveness (77 K, amplitude 2 mT, frequency 20 Hz – 10 kHz): > 120 dB
Field noise at 1 Hz (cooled at 77 K in zero field): < 50 fT/sqrt(Hz)
Critical temperature - zero resistivity: 108 K
Critical temperature - midpoint: 110 K
