摘要：

We introduce a novel containerless melt-spin processing technique for YBa2Cu3O7-x using prereacted oxide powders that are rapidly melted and subsequentially quenched in a controlled atmosphere. This results in flakes with typical dimensions of 3000 x 150 x 15-mu-m3. Powder XRD indicates that all samples contain Y2O3, but that the Ba-Cu-O phases present depend on the processing parameters. SEM and TEM studies show these phases are finely dispersed: the typical grain size for Y2O3 is 1-2-mu-m, and for the Ba-Cu-O phases it is < 0.5-mu-m.
