Oxidation studies of Y-Ba-Cu superconducting oxides

Abstract The oxidation characteristics of quenched samples of Y-Ba-Cu-O system, using thermogravimetric analysis (TGA); differential thermal analysis (DTA) and X-ray diffraction analysis, has been reported. A weight gain of 3.75% has been recorded in thermogravimetry experiment. The observed 3.75% change in weight of the quenched sample during heating or cooling cycle may be attributed to the multiphase compound formation due to decomposition reaction in the sample at 950°C.
