Copper (3) in complex oxides LnBa2Cu3O7-y
Description
By iodometric titration with subsequent binding of iodine with sodium thiosulfate copper (3) is determined in high-temperature superconductors LnBa2Cu3O7-y, where Ln=Y,Nd,Eu,Gd,Ho, and also in compounds Bi2(Tl)2(SrCa)3Cu2O8+x. It is shown that the average value of Cu3 content in the samples studied constitutes 24±2 % of total copper content
