Practical applications of the high-Tc ceramic superconductors will require electrical, mechanical and thermal stabilization of the superconducting phase. Non-noble metal superconducting particulate composites have been formed with various metals, in order to achieve some of the desirable properties. One of the critical parameters in forming superconducting composites with non-noble metals is the processing temperature of the composites, which is dictated primarily by the need to sinter the ceramic particles into a continuous superconducting skeleton. The possilbility to lower the processing temperature of the composites, by the use of Ag/Ag2O is explored. The relative effect of Ag and Ag2O on the low temperature sintering of Y1Ba2Cu3O7−x is discussed. The major difficulty in forming superconducting composites at low temperatures seems to be associated with poor contacts between the individual ceramic particles within the composite.
