  4. Bi2212 round wire vs Composite Reaction Texturing Source of distortion of the Bi2212 filaments: Retrograde densification and intergrowth (b) (c) (a) Applied Superconductors 259-filamentary Bi2212 round wire (a) as drawn; (b) after heat treatment (c) EDAX atomic mapping of Bi (darker area) of a fragment of heat treated wire; A schematic cross section of Bi2212/MgO-fibre composite (a) earlier stage of nucleation during cooling down and (b) final microstructure. MgO-fibre can be envisaged to align 2D random in plane. An SEM micrograph of a thermally etched cross section of CRT coating showing also the gold contact interface. (An end view of the MgO-fibre shown represent the MgO-f plane). TEM of the melt textured Bi2212 (Composite Reaction Textured)

  5. Oxygen doping optimisation of Coated Bi2212 conductor To ensure that x=8.21 can be retain during the slow cooling procedure, the constant parameters of temperature, To and a, were chosen as To=870ºC and a=60ºC. Schematic representation of the temperature and oxygen partial pressure dependence of the oxygen content, x, in Bi2Sr2CaCu2Ox phase; (1) sample slowly cooled under 0.21atm partial oxygen pressure, SC, and (2) sample SC(pO2). Applied Superconductors (a) (b) High-resolution transmission electron microscopy (HRTEM) images of low angle grain boundaries recorded from individual grains of: (a) a slowly cooled conductor under constant oxygen partial pressure of 0.21 atm, SC; (b) conductor cooled under under monotonically reduced partial pressure of oxygen SC(pO2). The temperature dependence of the transport Jc characteristics for tape SC(pO2) and SC.
