Mechanical Property Characterization of Na1/2Bi1/2TiO3-BaTiO3 Ceramics

Abstract—Bismuth based ferroelectric ceramics are drawing more attention due to being environmentally friendly. The studies are mainly focused on improving electrical properties of these ceramics, whereas studies on mechanical properties are scarce. Mechanical properties of solid solution of sodium bismuth titanate with barium titanate ((Na1/2Bi1/2)0.945Ba0.055TiO3) ceramics were studied and compared to those of PZT-4 ceramics. Three point bending strength, elastic modulus as well as indentation toughness were measured. It was found that the stress state with respect to the domain state plays an important role in determining the response to loading. An R-curve behavior was observed with increasing indentation load. The fracture toughness was found to be higher than PZT-4 ceramics. It was found that cracks encounter higher resistance to propagation when propagating in the poling direction.

Index Terms—Ferroelectric material, NBT, mechanical property, R-curve.
