dc.description.abstract | The ferroelectric properties of barium titanate strongly depend on its microstructure, in particular, grain size and distribution. During sintering, usually exhibits abnormal grain growth, which deteriorates considerably the ferroelectric properties. A typical technique to suppress the abnormal grain growth is the addition of dopants. Dopant addition, however, affects the ferroelectric properties and thus limits the application of . Here, we report a simple but novel technique to prevent the abnormal grain growth of and to overcome the limitation of dopant use. The technique consists of stepwise sintering in a reducing atmosphere and in an oxidizing atmosphere. The materials prepared by the present technique exhibit uniform grain size and high dielectric properties. The technique should provide opportunities of having -based materials with superior ferroelectric properties. | - |
