Abstract
The optimum calcination and sintering conditions for the preparation o f the desired phases with the proper stoichiometry of the bulk high-te mperature superconductors YBa2Cu3O7-x (YBCO) and Bi2Sr2CaCu2Oy (BSCCO) were investigated by differential scanning calorimetry. DSC analysis on the corresponding superconducting coatings, electrophoretically dep osited, indicated that the sintering and annealing procedure was suita ble for the production of stable, strong and adherent coatings. X-ray diffraction analysis, Raman spectroscopy and magnetic measurements con firmed the improved properties of the: superconducting powders and coa tings obtained.
