Abstract
A new method of preparation of bulk textured Bi2223 ceramics andBi2223+Ag composites, based on room temperature pressing of foamed precursor (Bi2223,Bi2223+Ag) in a liquid medium, is proposed. SEM and XRD data prove a high degree of texture ofthe bulk samples obtained. Magnetic measurements performed in directions -axis and -planes of Bi2223 crystallites demonstrates anisotropy of magnetization confirming thetexture of the ceramics. The materials obtained possess large diamagnetic response in thedirection -planes of Bi2223 crystallites at both 77.4 and 4.2 K.
