Preparation of highly oxidized RBa.sub.2 Cu.sub.4 O.sub.8 superconductors
Abstract
Novel superconducting materials in the form of compounds, structures or phases are formed by performing otherwise known syntheses in a highly oxidizing atmosphere rather than that created by molecular oxygen at atmospheric pressure or below. This leads to the successful synthesis of novel superconducting compounds which are thermodynamically stable at the conditions under which they are formed. The compounds and structures thus formed are substantially nonsusceptible to variations in their oxygen content when subjected to changing temperatures, thereby forming a temperature-stable substantially single phase crystal.
