FRAMSTAELLNING AV SUPRALEDANDE OXIDER OCH OXIDER OCH OXID-METALL-KOMPOSTION

摘要

A superconducting oxide is prepared by combining the metallic elements of the oxide to form an alloy, followed by oxidation of the alloy to form the oxide. Superconducting oxide-metal composites are prepared in which a noble metal phase intimately mixed with the oxide phase results in improved mechanical properties. The superconducting oxides and oxide-metal composites are provided in a variety of useful forms.
