Time-Dependent Compositional and Morphology Change of YBa2Cu3O7-x Semisolid Phase
Abstract
Microstructural development of platinum doped YBa2Cu3O7-x (Y123) semisolid melt, such as the loss of the liquid phase, morphology and size of Y2BaCuO5 (Y211) particles, has been studied using samples held for different duration time at 1050 C and quenched to the room temperature. Depletion of the liquid phase decreased as a function of the holding time while the width of acicular Y211 particles in the melt increased. Time dependent liquid loss from the semisolid melt was attributed to the capillary forces which were affected by the size of Y211 particles dispersed in the liquid phase. These observations may have important implications for the growth of large superconducting Y123 melt textured single crystals and their microstructural control.
