Bi2Sr2CaCu2Ox polycrystalline ceramics or the ceramics powder prepared by solid-state reaction was cupsulated in copper can with the dimensions of 22φ-14φ-65 ?? . The billet (can containing ceramics) preheated at a temparature of 840°C for 8 minutes, and then successfully extruded by pressing at a maximum load of about 34 ton. Phase stability, texturing of ceramics before and after the processing, and effect of the processing on the densification of extruded polycrystal were investigated in this reserch.
