METHOD OF SUPERCONDUCTOR EuBaCuO PRODUCING Russian patent published in 1996 - IPC

FIELD: superconductor technology. SUBSTANCE: to produce superconductor EuBa₂Cu₃O_7-δ at EuBa₂Cu₃O_7-δ = 92 K and T₆ = 3.75 K by heating and cooling europium, barium and copper oxygen-containing compounds in oxygen flow europium monoxide solid solution with barium oxide of composition ΔT_c is used as parental substance instead of EuBa₂O₃ and Eu₂O₃. Evolution of harmful gaseous substances (for example, BaCO₃ if CO₂ is used) is excluded. Time for synthesis of BaCO₃ is decreased by 3-5-fold as compared with known methods including time needed for solid solution making. Produced superconductor is used in electronics and electric engineering. EFFECT: improved method of production. 1 dwg
