Abstract
This study describes the use of spray-dried nitrate precursor powders in the synthesis of Bi-2223 high T-c-superconductors. The decomposition of the precursor powder is studied using TGA/DTA, XRD, IR, and nitrogen analyses. The particle size is determined using SEM. The low decomposition temperature of the nitrates (similar to 600 degrees C) and the small particle size of the spray dried powder (similar to 3.10(-6) m), resulting in a lowering of the calcination temperature and a shortening of the sinter time, enabled us to synthesize a > 96% pure Bi-2223 phase (from XRD peak intensities) after a thermal process of 5h at 650 degrees C and 60 h at 855 degrees C.
