摘要：
YBa2Cu3O7-x (123) pellets doped with 0.5 wt.% of PtO2. H2O were melt textured to determine the effects of PtO2 additions on the microstructure of melt textured 123. The addition of PtO2.H2O resulted in both a refinement and a change in the morphology of the Y2BaCuO5 (211) phase. The 211 particles are more acicular in melt textured PtO2-doped 123 than in undoped melt textured 123. The 211 particles were found to segregate and form tracks in the melt textured PtO2-doped 123 samples.
