The sintering behavior and electrical property of ceramics were investigated with the iron oxide concentration ranging from 0 to 5 mol%. Both the sintered density and grain size were found to increase up to 2 mol% , and then to decrease with further additions. At a higher content above 3 mol%, grain size decreased by a pinning effect induced by different shape grains. The electrical conductivity was also increased with increasing content up to 2 mol%. Total conductivity of 2 mol% specimen showed the maximum conductivity of at . The addition of was found to promote the sintering properties and electrical conductivities of .
