Synthesis, processing and characterization of high temperature superconducting YBa2Cu3O7-x samples were performed. Ceramic precursors with varying degrees of homogeneity were prepared using microemulsions and by organometallics precursors. The advantage these routes offer over conventional oxide powders is control over microstructural and compositional homogeneities. The formation of extraneous phases was eliminated and the presence of grain boundary phases (such as Cu2O) was brought to a minimum (0.5 vol %) through proper control of the microstructural development by colloidal processing and by densification. The importance of the heating schedule was emphasized in terms of oxygen intake, particularly in conjunction with cooling rates.
