  • Superconducting ceramics by sequential electrodeposition of metals, followed by oxidation
    Patent number: 5162295
    Abstract: The invention provides a method for forming deposits of superconducting ceramics by sequentially electrodepositing layers of metals, of a type and in proportion suitable for forming a superconducting ceramic, to form a precursor metal deposit, followed by oxidizing the precursor deposit to form a superconducting ceramic deposit. Optionally, the electroplating steps are conducted in such a manner that a patterned precursor deposit results, to obtain a patterned superconducting deposit after oxidation.
    Type: Grant
    Filed: August 6, 1990
    Date of Patent: November 10, 1992
    Assignee: Allied-Signal Inc.

  • Method of forming crystallite-oriented superconducting ceramics by electrodeposition and thin film superconducting ceramic made thereby
    Patent number: 4939308
    Abstract: The invention relates to an improvement in a method of forming deposits of superconducting ceramics. Generally, such ceramics are formed by electrodepositing a mixture of metals of the type and in proportions sufficient to be oxidized into ceramic; oxidizing the electrodeposited mixture under conditions sufficient to result in a superconducting ceramic deposit; and orienting the crystallites in said superconducting ceramic deposit. Crystallite orientation may take place before, after or during the oxidation step.

  • Method of forming superconducting ceramics by electrodeposition
    Patent number: 4879270
    Abstract: The invention relates to an improvement in a method of forming deposits of superconducting ceramics. Generally, such ceramics are formed by electrodepositing a mixture of metals of the type, and in proportions sufficient to be oxidized into ceramic, onto a substrate. The electrodeposited mixture is then oxidized under conditions sufficient to result in a super conducting ceramic deposit. The improvement resides in conducting the electrodeposition in a manner which results in a patterned electrodeposition prior to conducting oxidation.
