Heat Capacity of Scandium from 1 to 23°K

The heat capacity Cₚ of a well-characterized, polycrystalline scandium sample was measured from 0.9 to 23^∘{}K. The results are in reasonable agreement with previous measurements below 4^∘{}K, except that a small anomalous addendum to the heat capacity was detected, which is believed to be due to small concentrations of magnetic impurities in the sample. The results below 8.4^∘{}K after correction for the effect of impurities could be represented by the equation Cₚ=γT+(12Rπ⁴5)(TΘ)³, where γ=10.66±0.10 mJ deg^-2 (gat.)^-1 and Θ=359.5±4.2^∘K. A table of smoothed heat capacities and thermodynamic functions for scandium at selected temperatures between 5 and 298.15^∘{}K is presented.
