Effect of the pitch particle size on the thermal property of carbon foams

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.
