Woodceramics is a carbon material sintered from wood or woodymaterial to be used as an industrial material. All the woodceramics has the following characteristics: porous structure, light weight, hard property, heat resistance, anticorrosion and low cost in production. Today, the woodceramics is being studied for practical applications in various fields. In the present study, the electric conduction of woodceramics was investigated to use it as a porpous conductor in low temperature. The temperature dependence of electric resistance of the woodceramics was measured in low temperature and the carrier transport process was discussed. The temperature variation of resistivity was the same as that of semiconductor; it decreases with increasing temperature. This semiconductive behavior may be attributed to the intra-layer interaction of π-electron in graphite microcrystals.
