Abstract
The phase assemblage in PBSCCO precursor powders for 2223-OPIT production has been investigated in a quantitative way with Rietveld analysis of x-ray powder diffractograms. The investigated precursors were made by spray pyrolysis of solutions of the appropriate bulk chemical composition of Pb0.33Bi1.80Sr1.87Ca2.00Cu3.00O10+δ, and subsequent calcination to remove volatile elements and to form a suitable precursor phase assemblage at temperatures between 800°C and 820°C, in air or under reducing conditions. The influence of temperature and atmosphere on the powder quality was investigated with regard to different minor phases, and the Pb-content of the 2212-phase.
