METHOD OF PREPARING HIGH-TEMPERATURE SUPERCONDUCTING COATING Russian patent published in 1997 - IPC

FIELD: superconducting materials. SUBSTANCE: method includes preparing initial solution by mixing aqueous solution of nitrate salts of metals composing high-temperature superconducting material with summary concentration of cations not higher than 1.5 mol/l with solution containing at least 2 mol of citric acid and at least 7 mol of ethylene glycol per 1 mol of above-mentioned metal cations followed by curing resultant solution at 343-353 K to form viscous polymer solution, which is applied onto a carrier and thermal decomposition of applied layer is effected through high-speed heating at 1113-1193 K. method may be used to manufacture high-temperature superconducting wires and other superconductors finding use in computer technics, radiotechnics, and power engineering. EFFECT: optimized parameters of procedure. 2 cl, 1 tbl
