It has been found that only one composition of the series (n = 4), exhibited superconducting transition. Analysis by energy dispersive X-ray showed an increase of elemental ratio of Bi in all compositions. Activation energies of crystallization of various compositions are evaluated using thermal analysis and it is found that the activation energy plays a critical role in superconducting transition of these compounds. Structural analysis of the perovskites by XRD revealed a strikingly similar structure for all the compositions irrespective of their superconducting nature, while Raman and SEM revealed slight traces of impurity modes in all the compositions. However the impurity observed thus are minima in the lone composition that exhibited superconducting transition. Here an effort has been made to investigate the reasons for the only one composition of the series exhibiting superconducting transition irrespective of their near uniformity in the structure. It has been found that the presence of residual glass, plumbates and poor inter-grain connectivity formed the detrimental factors that made the two compositions devoid of their superconducting transition. | ||

Here an effort has been made to investigate the reasons for the only one composition of the series exhibiting superconducting transition irrespective of their near uniformity in the structure. It has been found that the presence of residual glass, plumbates and poor inter-grain connectivity formed the detrimental factors that made the two compositions devoid of their superconducting transition.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Melt quenching</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Avrami index</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Crystallization kinetics</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Activation energy</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">PBSCCO</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Predeep, P.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of thermal analysis and calorimetry</subfield><subfield code="d">Springer Netherlands, 1998</subfield><subfield code="g">114(2013), 2 vom: 08.

Abstract $ Bi_{1.6} $$ Pb_{0.4} $$ Sr_{2} $$ Ca_{n−1} $$ Cu_{n} $$ O_{x} $ perovskites system with n = 2, 2.5, and 4 synthesized through glassy precursor route by melt quenching. It has been found that only one composition of the series (n = 4), exhibited superconducting transition. Analysis by energy dispersive X-ray showed an increase of elemental ratio of Bi in all compositions. Activation energies of crystallization of various compositions are evaluated using thermal analysis and it is found that the activation energy plays a critical role in superconducting transition of these compounds. Structural analysis of the perovskites by XRD revealed a strikingly similar structure for all the compositions irrespective of their superconducting nature, while Raman and SEM revealed slight traces of impurity modes in all the compositions. However the impurity observed thus are minima in the lone composition that exhibited superconducting transition. Here an effort has been made to investigate the reasons for the only one composition of the series exhibiting superconducting transition irrespective of their near uniformity in the structure. It has been found that the presence of residual glass, plumbates and poor inter-grain connectivity formed the detrimental factors that made the two compositions devoid of their superconducting transition. © Akadémiai Kiadó, Budapest, Hungary 2013 |
