high t/sub c/ oxide superconductors can be prepared by a variety of novel metallurgical or ceramic processing techniques. for example, forming metallic precursors of yba/sub 2/cu/sub 3/ or reba/sub 2/cu/sub 3/, where re is a rare earth element, followed by oxidation has yielded the corresponding ceramic oxide in pellet, wire, and thin film forms. ceramic fabrication techniques such as doctor-blade tape casting and screen printing have been utilized to synthesize both tapes and thin films. in addition, it is likely that numerous laboratories are developing proprietary methods to fabricate wire and other forms but have not published these results the authors review some of the methods reported so far for preparing high t/sub c/ ceramic superconductors, and discuss one example of a proprietary method being developed at one of the author's (ldw) laboratories
