Abstract
The effect of YBa2Cu3O7-x grain size on the nucleation of Y2BaCuO5 was investigated by melt texturing of pellets with varying 1-2-3 grain si ze. In the absence of more effective heterogeneous nucleation sites, i t was found that the sintered 1-2-3 grain size affects the 2-1-1 parti cle size in subsequent melt-textured YBa2Cu3O7-x, with finer 1-2-3 gra in sizes yielding finer 2-1-1.
