Recently,lead-free ceramic materials have attracted attention from the viewpoint of environmental protection.BiFeO3(BFO)based solid solutions have been extensively studied,because BFO is also one of the few materials with coexistent ferroelectricity and antiferromagnetism at room temperature.But up to now,there are only few reports of making densified and high resistive BFO ceramics.The reason is maybe for the impurity phase,low density and high conductivity of the ceramic samples prepared by traditional method.
