Description
In Y-Ba-Cu-O systems high yield superconducting devices can be made from the top-quality bulk materials. The authors study the stability of bulk oxide compounds in order to search for a unique method to produce high Tc and hopefully shorten the period of processing. Systematic measurements of resistivity, magnetization, composition, and X-ray diffraction have been made on samples that have the same chemical prescription (pre-heating) but different heat processing. The processing was varied to find the optimum combination of the calcining time, sintering time, and annealing time at 650C. The authors have found that the Tc is stable if the dominant phase remains
