The Fe doped Ca1-xFexMnO3(x=00.12) powder and bulk samples are fabricated by citric acid sol-gel and ceramic preparation process, the samples are analzed by X-ray diffraction pattern and electrical constant measurement. The results show that all samples are of single phase, the lattice constants are gradually lowered by Fe doping for Ca site, and the crystalline grain growth is restrained. All the bulk samples have semiconductor transporting characteristics in the whole temperature range of measurement. The transportation mechanism is not changed. The energy for polarons to hop is increased for doped samples and thus the electrical resistivity is increased by increasing Fe doping concentration.
