Remarkable improvement in the magnetic shielding property of Bi(Pb) Sr Ca Cu O superconducting tubes, which were prepared by sintering rolled Bi (Pb) Sr Ca Cu O green sheets, has been achieved by applying intermediate cold isostatic pressing between the sintering treatments. The magnetic shielding property was increased from 4.0 to 7.0 mT by this modified process. Furthermore, the time dependence of the trapped magnetic fiux density was changed and the relaxation rate decreased also.
