Ceramics were used as a model to investigate the pore fabric originated during ductile deformation. The magnetic anisotropy was used to measure the pore fabric after pore saturation by a ferromagnetic fluid. The ductile deformation of the ceramics was investigated by measuring the magnetic anisotropy of dry specimens. The character and symmetry of the pore fabric are compatible with those of the deformations forming the fabric of the ceramics: in the linearly extruded ceramics, the pore fabric is dominantly prolate, while in the pressed ceramics it is dominantly oblate.
