Temperature Phase Diagram

ABSTRACTThe oxygen partial pressure - temperature phase diagram of YBCO type superconductors reported before by us showed that the YBa2Cu4Ox phase formation from Y2Ba4Cu7Oz with CuO, as well as from YBa2Cu3Oy, with CuO are oxidation reactions. The total gas pressure - temperature phase diagram shows that the YBa2Cu4Ox, phase formation temperature from Y2Ba4Cu7Oz with CuO increases with increasing the total gas pressure. On this phase boundary line, the fugacity of oxygen increases with increasing the total gas pressure even at constant oxygen partial pressure.

A detailed study has been made of the control and optimization of partial melting of dipcoated Bi2Sr2Ca1Cu2O8+δAg0.1 (Bi-2212) tapes using reduced oxygen partial pressures. A coulometric titration technique has been employed to vary the oxygen partial pressure in a region of the phase diagram corresponding to binary melting, and the amount of partial melting has been quantified. Using this information, tapes have been processed using both isothermal and isobaric techniques. An optimum processing route was determined which combined isothermal and isobaric processes. Highly aligned material at the point of optimum melting was obtained.
