Abstract

A stable shell of YBa₂Cu₄O₈ (124) forms in powder and sintered bulk YBa₂Cu₃O₇_-δ (123) superconducting oxides upon oxygen outdiffusion from the latter and serves as a diffusion barrier to retard further oxygen outdiffusion. The 124 phase formation has been investigated by thermogravimetric analysis and x-ray diffraction. The better thermal stability of the 124 phase can be explained by the stronger bonding configuration of O(1) atoms in a double-chain structure.
