Abstract
The effects of CeO2 and BaCeO3 additions on the microstructure of melt textured YBa2Cu3O7-delta and the extent of interactions between Ce-ba sed additions and the peritectic melt have been investigated. Both typ es of additions are effective in reducing the coarsening of Y2BaCuO5 p articles in the melt during texturing. This appears to be due, in part , to some Ce solubility in the melt which is thought to modify the 211 /liquid phase interfacial energy. (C) 1997 Elsevier Science B.V.
