This project will investigate the quaternary system, BaO-Y2O3-Cu-               O, by constructing sections of constant BaO content at different                oxygen partial pressures using a simultaneous thermal analyzer                  and quenching technique.  Compatible phases and melting                         relationships will be determined as a function of temperature and               oxygen partial pressure.  Measurements of electrical resistivity,               critical current, and magnetic susceptibility with temperature                  will be followed as a function of composition and state of                      oxidation of copper.  In addition, measurements of critical field               and heat capacities will be investigated between 1 K  and room                  temperature.  Conditions for growing single crystals from melt as               well as conditions for synthesis and processing polycrystalline                 material with the highest possible Tc will be established.
