The expression for the Josephson current flowing through the rectangular junctions was averaged over the values determining its properties in the case when magnetic field is less then first critical magnetic field of superconducting grains. The avera

Our experiments performed earlier have shown that, when an external magnetic field is absent, the transport critical current in 3-d superconducting ceramics is a homogeneous function of the sample transverse sizes. The transport critical current dens

It is shown that, when an external magnetic field is absent, the value of transport critical current in high-temperature superconducting ceramics is a power function of the sample cross-sectional area and independent of the variation of the sample cr

The temperature and size dependences of the critical currents in bismuth-based high-temperature superconducting ceramic samples consisting of randomly oriented grains have been studied in zero magnetic field. It is shown that the critical current is

The temperature and size dependence of the transport critical current in Y-123 and Bi-2223 + Bi-2212 HTSC ceramic sample has been studied. It is shown that the critical current may be presented as power function of cross section area, the critical cu

The effect of excess of Ca and Cu on superconducting and electrophysical properties of Bi-2223 ceramics was investigated. It was found that a certain excess of Ca and Cu in the nominal composition with relation to the stoichiometric one improves the
