Effect of Y2BaCuO5 Morphology and Size in Semisolid Melt on Growth Rate of YBa2Cu3O7-x Single Crystals
Abstract
To control the growth rate of melt textured YBa2Cu307. x (Y123) single crystals, the effects of starting powder composition and heating rate of the compacts on the morphology and size of Y2BaCuOs (Y211) in semisolid melt were studied. The processing route of the samples involved the mixture of Y2O3 and liquid phase composition (barium cuprate and copper oxide) as starting compounds. The correlations between the heating rate, the morphology of Y211, and the growth rate of Y123 ware examined. Observations from crystal size and microstructural analysis revealed that lower heating rate of compacts led to formation of needle shaped Y211 particles, which consequently resulted in faster growth rate of melt textured Y123 single crystal.
