Grain-orientation control of Bi5FeTi3O15 ceramics prepared by magnetic-field-assisted electrophoretic deposition

Abstract

Magnetic-field-assisted electrophoretic deposition (B-assisted EPD) method has been applied for synthesizing a(b)-axis-oriented Bi5FeTi3O15 ceramics, and the effects of the B-assisted EPD on grain orientation and microstructures have been investigated. The sintering at 1100 C of the green compact obtained by the B-assisted EPD led to dense ceramics with a high relative sintered density of 98 %. X-ray diffraction analysis shows that the a(b)-axis-orientation degree of the grain oriented ceramics evaluated by the Lotgering method was 45 %.
