The results show that the higher is the graphitization degree of carbon blocks, the higher is thermal diffusivity, α, at a given temperature; and α is decreased with the increment of temperature at a given graphitization degree. Resistance to thermal shock, R, of the carbon blocks was discussed from the experimental results.
