Abstract :	[en] This communication aims at reporting the superconducting properties of Dy-doped Bi-2212/NiO/Ni tapes prepared by a dip-coating process from an inorganic gel. The Bi-2212 is recrystallized at 965°C in presence of an external 1.2 T magnetic induction. The precursor gel, the temperature and the thermal treatment duration are optimized regarding the microstructure The resulting tape samples are characterized by electrical resistance and I-V curves. The presence of secondary phases, such as Bi-2201, is reduced after a 750°C annealing but Ni diffusion limits the critical current density of the as-obtained tapes. The magnetic critical current density measured on textured Dy-doped Bi-2212 monoliths, obtained with the same type of texturation process, but showing no Ni contamination, is found to be about 30 times larger than the critical current density of the tapes.
