Abstract
A method of preparing a superconducting oxide by combining the matalic elements of the oxide to form an alloy, folled 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.
Claims20
A method of preparing a superconducting oxide-metal composite, comprising the steps of:
- combining the metallic elements of a superconducting oxide in substantially stoichiometric proportions needed to form said superconducting oxide with a noble metal to form an alloy;
- and
- oxidizing said alloy under conditions sufficient to oxidize said metallic elements without oxidizing said noble metal to form a superconducting oxide-noble metal composite.
