Abstract The Byström–Evers compound Ag 5 Pb 2 O 6 was annealed at 500–540 K under a flow of electric current which results in a textured structure and anisotropic colossal electric conductivity (>10 9 Ω −1 cm −1 ) between 210 and 525 K. The related physical properties are primarily governed by dissociation of Ag from c ‐axis channels and lattice strains, which in turn depend upon electric current. (© 2004 WILEY‐VCH Verlag GmbH & Co.
