Wood and bamboo ceramics are newly developed porous carbon materials from wood and bamboo impregnated with resin, and they possess some special properties and can be expected to be used as electromagnetic materials, absorbents, catalyst carrier materials, etc. In this work, the graphitization behavior of wood and bamboo ceramics was investigated by X-ray diffraction. Experimental results show that the d(002) spacing of the bamboo carbon, wood and bamboo ceramics decreased and the apparent graphite crystallite size Lc((002)) increased with the increase of graphitization temperature. However, even after heat treatment at 3273 K, the d(002) and Lc((002)) value was only about 0.341 and 9 nm, respectively. These results indicate that all of the bamboo carbon, wood and bamboo ceramics investigated are typical non-graphitizable carbon or hard carbon.
