The paper presents the results of synthesis bismuth superconducting ceramics with compositions Bi1.6Pb0.4Sr2Can-1CunOy (n=2, 3, 5) based on amorphous obtained by ultrafast melt quenching. In order to increase rate formation compounds, effective devices have been developed for melting and hardening melts under action IR radiation. sample holder was made platinum. Melting were carried out in a co...
