“…The properties of antimony as a dopant are also uncertain. It was reported in [7] that doping of the Bi-Sr-Ca-Cu-O system by antimony leads to significant increase in T c (up to 160 K), but this result was not confirmed by other authors [8].…”

The effective dopants of , which formed phases compatible with the basic superconductor and did not cause the superconducting properties of Bi-2223 to deteriorate, was studied. It was found that the addition of 10 mol% of led to a reduction of the induction period and to an increase of the Bi-2223 phase content. It was shown that the surplus increased the amount of liquid in the system and thus accelerated the formation of Bi-2223 phase.

“…The Bi-2223 (or 110 K) phase has the highest critical temperature in this system. In order to obtain a homogeneous single-phase material, different methods such as careful adjustment of the thermal treatment [1,2], sintering under reduced oxygen partial pressure [3] doping with Pb atoms [4,5], the liquid ammonium nitrate method [6,7] etc. are employed.…”

Ac susceptibility measurements on ceramic samples with the nominal composition of Bi 1:8 Pb 0:4 Sr 2 Ca 2 Cu 3 O 10Àd prepared by various pressing pressures on the pellets (355, 533, 711 and 1067 MPa) and different directional cooling temperature rates (20, 10, and 5 C/h) using a directional solidification approach with a stationary Pt crucible in a strong temperature gradient have been carried out. The intergranular critical current density (J cm ) distribution has been calculated from ac susceptibility measurements by using Bean's and Kim's critical state models. It is observed that the critical current density improved with increasing pressing pressure and decreasing directional cooling temperature rates.
