Fabrication of Y123 disk by the seeded infiltration and growth method

The seeded infiltration and growth process was used to prepare disks of Y123. This process produces a net-shape product with a uniform distribution of Y211 with a majority of the particles under 2 μm. The Y211 area fraction remained constant at about 27% for different cooling rates in the range 0.5–4°C/h. The critical current density at 77 K was determined to be in excess of 100 000 A/cm² under zero field and about 20 000 A/cm² under 1.5 T magnetic field, which indicates that this method is a good replacement for the conventional melt-texturing process.
