Heat Capacity of Tungsten between 4 and 15°K

Abstract

The heat capacity of tungsten was determined in the temperature range 4 to 15\ifmmode^\circ\else\textdegree\fi{}K. The results obtained can be represented by the equation: $C(\mathrm{joules}/\mathrm{mole}\mathrm{deg})=1.11\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}3}T+1943{(\frac{T}{378})}^{3}$, with an average deviation of about one percent. The electronic specific heat coefficient and the Debye $\ensuremath{\theta}$ are evaluated to be (1.1\ifmmode\pm\else\textpm\fi{}0.1)\ifmmode\times\else\texttimes\fi{}${10}^{\ensuremath{-}3}$ joules/mole ${\mathrm{deg}}^{2}$ and 378\ifmmode\pm\else\textpm\fi{}7\ifmmode^\circ\else\textdegree\fi{}K, respectively. The results are compared with the theoretical calculations of Fine and of Manning and Chodorow and with measurements by other investigators in neighboring temperature ranges.
