Continuous silver‐clad Y‐123 wire has been fabricated from cofired green fibers produced by melt‐spinning polymers loaded with Y‐123 powders. Metal claddings are provided by coating with silver‐alloy powder slurries. The sintered polycrystalline Y‐123 wires have 77 K self‐field critical current density ( J c ) values up to 2900 A/cm 2 , with typical ranges in long lengths of about 1000 A/cm 2 , but are weak linked. High‐ J c wire is made by continuous melt texturing of the presintered wires. Values of J c above 10 000 A/cm 2 at 77 K have been achieved.
