Abstract

The infiltration driving force and the growth mechanism of the liquid infiltration and seeded growth process on YBa2Cu3O7-x were studied. The main driving force for the liquid infiltration is either the capillary force or the chemical potential, while gravity does not play a significant role and may be neglected. The particle size and distribution of the Y-211 inclusions of the final Y-123 specimen prepared by the liquid infiltration and seeded growth process are solely determined by the particle size and distribution of the Y-211 preform. The critical current density at 77 K was determined to be 80000 A cm-2 under self-field and 35000 A cm-2 under 1.5 T. The superconducting properties are highly enhanced using this method compared to the conventional melt texture growth process.
