Continuous solidification of YBa2Cu3O7−x by isothermal undercooling

Multiseeded melt growth of bulk Y–Ba–Cu–O using thin film seeds

“…[1][2] As a result, increasing the growth rate of large, single 3 grains is highly desirable for the growth of bulk samples with good superconducting properties.…”

“…This time-consuming procedure causes a variety of problems, such as self-induced crystallization and Ostwald ripening of non-superconducting Y 2 BaCuO 5 (Y-211) particles at the growth temperature, which interfere with the growth process and degrade the flux pinning properties of the YBCO bulk grain. [1][2] As a result, increasing the growth rate of large, single grains is highly desirable for the growth of bulk samples with good superconducting properties.…”

Nanoparticulate composites of melt textured YBa2Cu3O7−x superconductors

“…However, the size of the Ba 4 CuPt 2 O 9 clusters was in the range of hundreds of micrometers. 16 On the other hand, nanosized platinum- containing inclusions as well dispersed particles were observed in the Nd-Pt-Y123 system as shown in Fig. 7.…”

“…It has been reported that addition of platinum in Y123 system typically results in the formation of the Ba 4 CuPt 2 O 9 compound. 16 Results from the microstructural analysis suggested that the presence of Nd in Y123 may play a role in controlling the size of platinum based inclusions. It has been observed that addition of platinum in Y123 samples could lead to the formation of clustered Ba 4 CuPt 2 O 9 particles.…”

Study on single domain growth of Ag-doped Sm–Ba–Cu–O bulk using cold seeding technique

“…Slower dissolution rate of coarsening Sm211 particles results in a lower growth rate, as in the case of YBCO system [23]. Hence, during the initial stage of solidification, a relatively fast dissolution of smaller Sm211 particles takes place which corresponds to a higher growth rate of Sm123.…”
