In this research, the influence of the pitch particle size on the thermal diffusivity of the carbon foam was studied. The results indicate that the thermal diffusivity increases from 12.3 mm 2 /s to 23.09 mm 2 /s with an increasing pitch particle size from <500 mesh to 100-200 mesh, because the carbon foam produced by using larger pitch particle has highly aligned graphitic structures with less cracks and folded texture and its degree of graphitization is higher.
