Thermophysical properties of MPG-6 graphite
Annotation
The thermal diffusivity and heat capacity of four MPG-6 graphite samples (density from $1664$ up to $1825\text{ kg/m}^3$) are measured within the temperature range from $293$ K up to $1650$ K by the following methods: the laser flash, the differential scanning calorimetry, and the adiabatic calorimeter of linear heating. The uncertainties of the data on the thermal diffusivity, heat capacity, and density were $(2$–$4)\%$, $(3$–$5)\%$, and $0.5\%$, respectively. On the basis of the measurement results, the temperature dependence of the MPG-6 thermal conductivity is calculated and a generalizing dependence is obtained which allows one to estimate the thermal conductivity of graphite of various porosity for a wide temperature range using only the data on the macroscopic density of the samples. Reference data tables have been developed for the thermal conductivity of MPG-6 graphite of various densities.
