Technological applications of high temperature superconductors will be possible only for bulk samples or thin films exhibiting high critical current density. The strong anisotropy of the critical current density in YBaCuO gives rise to new interest in texture analysis. Several processing techniques have been developed for the specific purpose of increasing the preferred grain orientation in ceramics. Quantitative texture studies of oriented YBa2Cu3O7-delta bulk samples or films have been carried out by X-ray diffraction pole figures using the Schulz reflection technique. The (00l) pole figures define the c axis alignement while the (103) and (113) pole figures give information on the rotation about the c axis.
