Abstract
Bi2Sr2CaCu2Ox ceramic powder prepared by solied-state reaction was encupsulated in SUS304 stainless steel mold with dimentions of 20φ(O.D.) - 10φ(I.D.) × 30hmm. The mold were heated at 840°C for 10 minutes and were press-forged rapidly under various uniaxial compressive loads to avoid excessive heat loss. Density of the processed ceramics was estimated from the results of Vickers hardness(Hv) measurment. The Orientation degree(f) of the superconducting (00l) plane of the crystal grains was determined by an X-ray diffraction analysis of the polished surface of the ceramics. The values of Hv and f increased with an increase in the deformation ratio of the mold during the processing.
