摘要

Shielding elements were made of bulk material or thick films. The bulk route is determined by large-scale processing. After an axial or isostatic pressing of the fine-grained powder composed of BSCCO. Y-123 and Nd-123, the material was sintered/textured and annealed in special programs. Then the characterization of the materials and it measurement of magnetic fields was done with the help of a specially constructed measuring apparatus with Hall- and SQUID-sensors. The objective of the thick film route was to get large. coated superconducting work pieces of YBCO and BSCCO (plates or cylinders) with current density of > 1000 kA/cm(2) (and/or a shielding effect of .1 mT), Thick films were made by plasma spraying and paste technology. Substrates used were ZrO2, MgO, SrTiO3. BaZrO3 and others. In some cases the work pieces were treated with laser radiation, After laser and thermal treatment the surface was more dense, the cracks were cured and the current density was increased by more than two times, (C) 2002 Elsevier Science B.V.
