摘要：

A process technique is described which results in significant surface texturing of bulk YBa//2Cu//3O//7// minus // delta samples. Using standard calcining and sintering cycles, surface textured material with grain size greater than equivalent to 50 mu m has been produced. The T//c of the material is 93 K and J//c (transport), for predominantly textured material, is in excess of 1. 5 multiplied by 10**3 A cm** minus **2 in zero applied field at 77 K.
