The Removal of Organics from Tape Cast YBa2Cu3O7−x
The decomposition of tape cast YBa2Cu3O7−x during the removal of organics was studied using X-ray diffraction (XRD) and thermal gravimetric analyses (TGA). The YBa2Cu3O7−x phase decomposes in the presence of carbon dioxide and water produced from the volatilization of organic matter, forming an intermediate carbonate phase. This carbonate phase was found to decompose at higher temperatures upsetting the stoichiometry of the YBa2Cu3O7−x phase and producing some barium cuprate phase (Ba2Cu3O5).
