Abstract

International audience; The formation pathway of ( Tl0.5Pb0.5)( Sr0.9Ba0.1)(2)Ca2Cu3Oz and (Tl0.5Pb0.5)(Sr0.8Ba0.2)(2)Ca2Cu3Oz was studied by neutron and x- ray diffraction. The following reaction pathway was proposed: thallium oxide and lead oxide react with Sr- rich ( Sr(1-x)Cax) CuO2 and Ca-rich ( CaxSr1-x)O to form Sr4Tl2O7 and ( Cax Sr1-x) PbO3, respectively. The thallate and the plumbate compounds then form the ( Tl0.5Pb0.5)-1212 phase starting at a temperature of 600 degrees C. Finally, between 850 and 900 degrees C, the 1223 phase is formed from (Tl0.5Pb0.5)-1212, ( CaxSr1-x)(2)CuO3 and CuO. Parallel experiments to fabricate the ( Tl, Pb)- 1223 superconductor resulted in specimens with critical temperatures of 117.5 K and 116 K, respectively, and transition widths of 2 K. Differences between the pathways for the formation of Pb- doped, Sr- rich and Pb- free, Ba- rich Tl- 1223 superconductors are discussed.

19. Structural refinements on high-Tcsuperconductor Tl0.5Pb0.5Sr2−xBaxCa2Cu3O9−δ

Abstract

Samples of nominal composition Tl0.5Pb0.5Sr2−xBaxCa2Cu3O9−δwith 0≤x≤0.6 were characterized by structural refinements on X-ray powder diffraction data. The weight fraction of the 1223 phase ranged from 85% (x=0) to 91% (x=0.4); 1212 phase, (Ca, Sr)2PbO4, (Ca, Sr)2CuO3and BaPbO3being detected in small quantities. The refined Ba content in the 1223 phase corresponded to the nominal compositions and the cell parameters increased with increasing x. The distance between the Cu atom and the apical O atom of the square pyramid increased from 2.29 to 2.50 Å as the Ba content was raised. A displacement (up to 0.26 Å) of the Tl atoms from the ideal position on the 4-fold axis was observed for all samples. Structural refinements on neutron diffraction data indicated related displacement of the O atoms in the TlO layer. Tcwas not significantly affected by the changes in composition and structure and ranged from 118 K (x=0) to 116 K (x=0.6).
