Abstract

In the present study the maximum oxygen contents of the superconducting oxides, YBa₂Cu₃O_7-x have been determined by the thermogravimetric analysis (TGA). Decomposition reactions in hydrogen atmosphere were also determined by the X-ray diffraction analysis, especially by considering the several inflections exhibited in the TGA curve of YBa₂Cu₃O_7-x in hydrogen reduction to 950°C. Particular decomposition reaction at the long plateau of 615-760°C has been identified as chemical reactions, Ba₄Y₂O₇ → Ba₂Y₂O₅ + 2BaO and 3BaCuO₂ → Ba₂Cu₃O₅ + BaO_x without weight loss.
