[all data], Butland and Maddison, 1973 Specifi c heat of graphene and graphite The specific heat, C, of a material represents the change in energy density U when the temperature changes by 1 K, C = d U /d T, where T is the absolute temperature. Therm. Khim., 1973, 7, 1824-1827. Your institution may already be a subscriber. T = 300 to 420 K. Cp value reported at 298 K is 0.685 J/kg*K.; T = 80 to 300 K. Cp = 8.729x10-4T + 6.27x10-6T2 + 6.309x10-9T3 J/g*K. Value calculated from equation.

In the Debye equation, K is directly proportional to the mean free path, L, which is turn is inversely proportional to temperature due to the increase in vibration amplitude of the thermally excited carbon atoms. Metrologia, In an adiabatic vacuum calorimeter, a temperature dependence of heat capacity of four allotropic modifications of carbon, viz, synthetic diamond, graphite, carbyne and fullerene C 60, has been studied in the (5–340) K range.

Upon irradiation in a reactor, a number of significant changes take place driven by different components of the radiation field to which the graphite is exposed. The specific heat of high‐purity Acheson graphite prepared by the National Carbon Company has been measured from 13° to 300°K. By its nature, the second method reduces systematic effects. and Informatics, X-ray Photoelectron Spectroscopy Database, version 4.1, NIST / TRC Web Thermo Tables, "lite" edition (thermophysical and thermochemical data), NIST / TRC Web Thermo Tables, professional edition (thermophysical and thermochemical data).
