Abstract
The Heat Exchanger Method (HEM) has been used to prepare bulk textured Yba2Cu3O7-x ceramics. The experimental process and the thermal parame ters used for texturing are described. The resulting bulk textured cer amics have been investigated by X-ray diffraction, optical and scannin g electronic microscopies. A 92 K temperature transition and a J(c) of 5 000 A/cm2 at 77 K in the absence of magnetic field have been shown by ac susceptibility measurements.
