Abstract

We experimented with investigation of the model of electrochemical reduction in electrochemical treatment on Bi₂Sr₂CaCu₂O_Y superconductor by using methyl alcohol as solvent and three materials: Ca(NO₃)₂⋅4H₂O, CuSO₄⋅5H₂O and Cu(NO₃)₂⋅3H₂O as solutes. The samples before and after the treatment were investigaited by X-ray diffraction, fluorescent X-ray analysis and resistivity measurement.<BR>As a result, we suggested two model of reduction such as<BR>(1)Bi₂Sr₂CaCu₂O₈+ (x+y)Ca²⁺+ 2(x+y)e^-→Bi₂Sr₂Ca_1+xCu₂O₈+ yCa<BR>(2)Bi₂Sr₂CaCu₂O₈+ (x+y)Cu²⁺+ 2(x+y)e^-→ Bi₂Sr₂CaCu_2+XO₈+ yCu<BR>where (x+y) is constant in each quantity of electricity and y is much greater than x. However x and y were so randomly variable that it was very difficult to control of electrochemical reduction.
