Series of the samples with nominal compositions Bi 3.2 Pb 0.8 Sr 4 Ca 5 Cu 7 O x and Bi 3.2 Pb 0.8 Sr 4 Ca 5 Cu 7 O x / Ag (10 wt%) were prepared by the standard solid state reaction at the same calcination and sintering temperature and time. Three starting mixtures were used, carbonates, oxides and silver i) with nanoparticles, ii) with micrometer size of particles and iii) powder obtained by modified sol-gel process. The main phase in all samples was Bi -2223 and silver formed the separate phase. The sol-gel process was found to be effective way in term of porosity, bulk density and connectivity of the grains. The effect of the microstructure on the transport properties were described by the temperature dependence of resistivity and critical current densities.
