Abstract

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 non- steamed 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%.
