| dc.description | (Sm211) refinement was achieved in Sm-Ba-Cu-O systems melt-textured at various oxygen partial pressures ( of 0.001 - 1 atm) via 1 wt% addition and size control of a precursor powder (a mixture of (Sm123) plus Sm211 powder) by means of attrition milling. The resulting Sm211 of the (Sm1.8) sample melt-textured without addition was as large as a few tens of while the Sm211 of the Sm1.8 sample melt-textured from the attrition-milled powder with 1 wt% addition was as small as 1 - , with uniform Sm211 distribution. The Sm211 refinement achieved is ascribable to both the controlled Sm211 nucleation during incongruent melting and the growth inhibition of the Sm211 in the partial melting state. Furthermore, the Sm211 shape was changed from equiaxed granular in the undoped sample to anisotropic in the samples containing . Effects of oxygen partial pressure on the Sm211 size and the shape was not significant in either the undoped Sm1.8 sample and the -added Sm1.8 sample. |
