PREPARATION OF SUPER-CONDUCTING PHASE BASED ON BISMUTH, STRONTIUM, CALCIUM, COPPER AND STABILIZING ELEMENT

摘要

PURPOSE: To easily obtain a superconducting product expressed in a formula in a short time by drying a solution containing Bi, Sr, Ca, Cu and stabilized elements, and burning it in an atmosphere. ;CONSTITUTION: The solution containing Bi, Sr, Ca, Cu and stabilized elements (Pb, Sa and Sn) is prepared. This solution is dried by being spouted into a high-temperature substrate. Next, this dry product is burnt in the atmosphere. Then, the superconducting product shown by Bi_xM_ySv_zCa_tCu_vO_w (X; 1.5±0.2, Y; 0.5±0.2, Z; 2±0.5, t; 2±0.5, V; 3±1, M; Pb, Sb, Sn and W: determined from the valences of respective cations) is obtained.;COPYRIGHT: (C)1992,JPO
