Thermal Conductivity of the Elements

Abstract

This is the abridged version of a comprehensive volume on the thermal conductivity of the elements. It contains recommended reference values resulting from critical evaluation, analysis, and synthesis of all the available data. It also gives estimated values for those elements for which no thermal conductivity data are available. Thus, the work provides recommended or estimated thermal conductivity values for all the elements over the full temperature ranges where experimental data are available or reliable extrapolations or estimations can be made. The results on each element are presented in both graphical and tabular forms. Summary graphs arranged by group in the periodic table are also given.

Temperature-Dependent Mean Free Path Spectra of Thermal Phonons Along the c-Axis of Graphite

“…Considering the measured thermal conductivity is independent of thickness, these boundaries must consist of internal grain boundaries. The trend of the curve as well as the peak position are consistent with prior experimental and theoretical works [32,33]. The measured bulk thermal conductivity at room temperature is between 6.4 W/mK to 7.0 W/mK, in agreement with the accepted value of 6.8 W/mK [14].…”

Electrical Resistivity of Aluminum and Manganese

“…(3a) reduces to -, (4) while at high temperatures (T >) R), to a good approximation, it reduces to Pi ~ 101…”

Temperature of a nanoparticle above a substrate under radiative heating and cooling

“…For the problem discussed here, we can find that the thermal resistance by radiation Z rad = ∆ T /(P rad (T ) − P rad (T b ))= ∆ T /(Q abs I inc πR 2 ) ≈ 1.27 10 17 ∆ T (in Kelvin/Watt). It is worth to mention that regardless of the value of ∆ T (> 1 K), the value of Z rad is always much smaller than the thermal resistance by conduction inside the NP Z cond ≈ 1/(2 κ Au R)= 6.3 10 4 Kelvin/Watt (κ Au =317 W/(m.K) at T = 300 K [33]). This is perfectly consistent with the assumption that the temperature inside the NP is uniform.…”
