Electrical Properties of Woodceramics Made from Thinned Logs of Cryptomeria japonica D.DON

Woodceramics are new porous carbon materials obtained by carbonization of wood or woody materials impregnated with thermosetting resin in a vacuum furnace. This study examined the electrical properties of woodceramics made from thinned logs of Cryptomeria japonica as a use for electric articles. The summarized results were as follows: 1. The volume resistivity of woodceramics decreased with increasing density of woodceramics made from 3 type board. And the volume resistivity of woodceramics made from nonsteamed board was somewhat higher than steamed board. 2. The consumption of electric power of woodceramics decreased with increasing density of woodceramics and resin contents made from 3 type board. And the consumption of electric power of woodceramics made from non-steamed board was somewhat higher than steamed board. 3. When the woodceramics were coated by silicon, the consumption of electric power increased about 7%.
