Bi 5AgNb 4O 18 is a new phase, which was discovered during the phase equilibrium study of the Bi 2O 3-Ag 2O-Nb 2O 5 system. Bi 5AgNb 4O 18 was prepared at 750 C and is stable in air up to its melting temperature of 1160.1 5.0 C. Results of a Rietveld

Phase Equilibria of Ba-R-Cu-O-F-OH for Coated-Conductor Applications (R=Lanthanides and Y)

August 1, 2004
Author(s)
Winnie K. Wong-Ng, Lawrence P. Cook, Igor Levin, J Suh, Ron Feenstra, T J. Haugan, P. D. Barnes
Phase diagrams of the Ba 2RCu 3O 6+x (R=Nd, Sm, Gd, Y, and Er) superconductors, prepared under 0.1 % 0 2 at 810 C, reflect the trend of the lanthanide contraction. The single-phase regions of Ba 2-x(Nd 1+x-yR y) Cu 3O 6+z for R=Gd, Y and Yb, and Ba 2-x(R 1

Phase Relationships in the BaO-Sm 2 O 3 -CuO x System Under 100Pa O 2

By applying controlled atmosphere methods to minimize the presence of carbonate, and CO 2 and H 2O contamination, subsolidus phase equilibria of the BaO-Sm 2O 3-CuOx system at pO 2 = 100 Pa (0.1 % O 2 by volume) were successfully determined. Under

Flux Loss Measurements of Ag- Sheathed Bi-2223 Tapes
