Abstract

Woodceramics are new porous carbon materials obtained by burning wood or woody material impregnated with thermosetting resin in a vacuum furnace. In this paper, the effect of burning temperature on the structural changes of Woodceramics is analyzed experimentally.

Woodceramics were prepared using medium density fiberboard which was burned at temperatures less than 1000°C in a charcoal kiln. A drastic decrease in dimensions and weight was observed at temperatures lower than 600°C but they decreased gradually at temperatures higher than 600°C. Reproducibility of dimensions and weight by burning is possible.

When Woodceramics were prepared by burning at higher than 1600°C by high frequency induction furnace, dimensions and weight decreased due to transformation of amorphous carbon to graphite, but the porous structure of wood remains unchanged.

The distribution of glassy carbon and amorphous carbon was difficult to decipher after graphitization by observation with SEM and X-ray diffraction analysis.
