Abstract
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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
87 words
In a method of forming deposits of superconducting ceramics comprising the steps of (a) electrodepositing onto a substrate a mixture of metals, of the type and in proportions sufficient to be oxidized into ceramic, and (b) oxidizing said electrodeposited mixture on said substrate, under conditions sufficient to result in a superconducting ceramic deposit, the improvement wherein the electrodepositing step is conducted in a manner such that a patterned deposit results, with said oxidation step being conducted on said patterned deposit to result in a patterned superconducting deposit.
Claim 2
Dependent Claim
87 words
In a method of forming deposits of superconducting ceramics comprising the steps of (a) electrodepositing onto a substrate a mixture of metals, of the type and in proportions sufficient to be oxidized into ceramic, and (b) oxidizing said electrodeposited mixture on said substrate, under conditions sufficient to result in a superconducting ceramic deposit, the improvement wherein the electrodepositing step is conducted in a manner such that a patterned deposit results, with said oxidation step being conducted on said patterned deposit to result in a patterned superconducting deposit.
Claim 3
Dependent Claim
29 words
