Formation of the high temperature Bi-2223 phase has been studied for samples with nominal composition Bi 3,2-x Pb 0.8 M x Sr 4 Ca 5 Cu 7 O y. M represented V, Nb, Ta, their contents was altered from 0 to 0.6 mol %. The effect of the additives on the growth of the phase 2223, lattice parameters and the superconducting properties of the samples was detected. It was found that the additives enhanced the volume of the 2223 phase, improved the intergrain connection resp. the critical current density. The additives did not affect the lattice parameters and T c significantly.
