Abstract

In the present paper the structure, phase composition, superconducting properties and transport current for (BiPb)2Sr2Ca2Cu3Oy doped by TiC and NbC are investigated and their characteristics are presented. Concentration of impurities-was varied from 0.5 to 4.0 wt %. It was found that TiC impurity doesn 't affect on superconducting properties of specimens when its concentration less than 2 wt %. It was observed that superconducting properties of Bicontaining compounds are significantly suppressed with introducing of the same quantity of NbC impurity.
