Abstract

A mixture suitable for the production of melt-processed high-temperature superconductors capable of producing a high levitation force. The mixture contains YBa.sub.2 Cu.sub.3 O.sub.7-x powder with a very low content of copper oxide, i.e. copper not bound in with the YBa.sub.2 Cu.sub.3 O.sub.7-x, and a very low carbon content. Also included are stabilizing (so-called "flux-pinning") additives. Also disclosed is a method or producing the mixture, as well as YBa.sub.2 Cu.sub.3 O.sub.7-x powder with suitable low free copper oxide and carbon contents, used to prepare the mixture.
