Activation Energy of Decomposition of Y2bacuo5 Compound in Wet Co2 at Elevated Temperatures

  • John J. Simmins (a1), Michael J. Hanagan (a1), Gary S. Fischman (a1) and Robert L. Snyder (a1)


Decomposition of the Y2BaCuO5 in C02 was studied using simultaneous thermal analysis (STA) and X-ray diffraction (XRD). The time derivative to the thermo-gravimetric analysis data (DTG) was used to calculate the activation energy. The activation energy of decomposition by CO2 into barium carbonate, copper oxide and yttrium oxide was found to be <
