Özet:

 

The formation of hot zone by electric field on  superconducting Bi-Pb-Sr-Ca-Cu-O (BSCCO) rods is described.  Bulk  samples with a nominal composition of Bi1.6Pb0.4Sr2Ca3Cu4Ox  (2234) were prepared as rods by a melt casting process.  An electrical  field was applied to the BSCCO rods and this current caused the  resistance of the rod to fall and after a few minutes the initial  voltage fell while the current was increased to 2.5A. Under certain  conditions, a well-defined hot zone formed at the positive electrode,  travelled along the rod and eventually disappeared on reaching the  negative electrode.  A small increase in the applied current when the  zone approached the negative electrode produced another zone at the  positive electrode which then exhibited similar behaviour to the  first.  Reversing the polarity caused the zone to travel in the  opposite direction.  The rods were characterized by means of  microstructural and physical property studies.  The results of this  metod indicates a possible alternative processing route for  crystallization of the glassy BSCCO rods and producing superconducting  phase.
