Synthesis and Study of Microstructural Features of BSCCO-2223 Superconductors

Nigvendra Kumar Sharma [3]


Abstract: The samples of 2223 compound of BSCCO system superconductors were synthesized by using solid state reaction techniques. The samples calcined at 830 ?C and sintered at 845 ?C showed higher Tc values. The highest value of Tc(R=0) at 84 K has been observed in the case of sample calcined at 830 ?C and sintered at 845 ?C. The study reveals that the calcination around 830?C is advisable for getting the samples with higher values of Tc. The high-resolution transmission electron microscopy (HRTEM) and electron diffraction technique was used to ascertain the presence of 2201, 2212 and 2223 phases in these materials. The transmission electron microscopy and electron diffraction studies revealed the presence of lattice planes, rotational Moire fringes, formation of Bands, and grain boundaries etc. in these samples at some typical regions. The microstructural features of these samples were discussed in relation with the results R-T measurements.
