【 摘 要 】

The article presents the research results on the synthesis of HTSC ceramics using concentrated radiant radiation. It was established that all synthesized samples of the nominal composition Bi17Pb03Sr2Can-1CunOy (n = 3, 4, 5), the main phase was the superconducting phase Bi17Pb03Sr2Can-2CunOy, which has a critical temperature of the transition to the superconducting condition of 107 K. Also in samples of nominal compositions Bi1,7Pb0,3Sr2Can-1CunOy (n = 4, 5) showed traces of phases with higher T c.
