“…The importance of (rare earth)-Ba-Cu-O (REBCO) large grain materials has been demonstrated repeatedly by the achievement of high critical current densities (J c ) [1], the manipulation of the J c peak effect [2], the reproducible fabrication of large single grains and the exploitation of such materials in magnetic bearings [3][4][5], current leads [6][7][8] and motors [9]. YBCO large grains are the most well developed materials in the REBCO series.…”

Correlations among seeding temperature, the aspect ratio of NdBCO seeds and the growth morphologies of NdBCO-Ag grains have been conducted in detail. On the basis of these correlations, large c-axis-oriented NdBCO-Ag superconducting grains were fabricated using NdBCO seeds and a simple processing system which does not require detailed control of oxygen partial pressure. These NdBCO-Ag grains exhibited superconducting properties similar to NdBCO materials. In view of the simplicity of the processing system and the effectiveness of the seeding technique, scaling-up of the production of NdBCO-Ag large grain materials for engineering applications could be possible.

“…The potential of applying large grain materials of superconducting (rare earth)-Ba-Cu-O (REBCO) in different engineering devices has been well demonstrated: they have given rise to the development of highperformance magnetic bearings, 1-4 current leads, [5][6][7] and motors. 8 Apart from the intrinsic properties of these materials and their reproducible production in large quantities, the usefulness of these materials lies in achieving high critical current densities (J c ), 9 as well as the manipulation of J c peak effect in a magnetic field, 10 which flows over a large dimension.…”

NdBCO large-grain materials can improve the performance of engineering devices based on superconducting bulk materials if c-axis-oriented large grains can be produced in large quantities under simple processing conditions. This study concentrates on exploring the factors dictating the seeding behavior and the subsequent growth morphology of Ag-doped NdBCO grains under relatively high oxygen partial pressure using NdBCO seeds and a simple processing system. It was found that seeding temperature, aspect ratio of seed, and amount of Ag were all important factors affecting the success rate of inducing c-axis-oriented growths. With the optimized seeding conditions and in view of the simplicity of the processing system, the processing conditions derived from this study could lead to the up-scaling of NdBCO-Ag large-grain materials production.
