This paper reports sheathed high-T{sub c} superconducting ceramic wire composites fabricated by wire drawing. Superconducting powders of YBa{sub 2}Cu{sub 3}O{sub 7 {minus} x} (Y {minus} 123) and Bi{sub 4}(Sr,Ca){sub 6}Cu{sub 4}{sub 16 + x}(Bi {minus} 464) have both been prepared and successfully fabricated into continuous wire form. Under certain circumstances, a displacement reaction occurs at the interface between the ceramic superconductor and the containment tube; the nature of this displacement reaction and its prevention are discussed. Microcracking of the ceramic core is attributable predominantly to relative shrinkage effects during sintering. Failure of the metal wall during wire fabrication is attributed to drawing conditions and the mechanical properties of core and cladding.
