Abstract
A method of preparing a superconducting oxide 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.
Claims17
A method of preparing a copper oxide-based superconducting oxide, comprising the steps of:
- combining the metallic elements of a copper oxide-based superconducting oxide in substantially stoichiometric proportions needed to form said superconducting oxide to form an alloy;
- and
- oxidizing said alloy to form said copper oxide-based superconducting oxide.
