Abstract

The heat capacity of α-quartz has been computed over the temperature range 10–700°K, and that of vitreous silica from 10° to 900°K. Debye θ's obtained from the T3 law below 10° were used for the ``translational'' degrees of freedom, and recent infrared and Raman data for the other frequencies. Cp—Cv was negligible for vitreous silica and was computed from compressibility and thermal-expansion data for α-quartz. Agreement with new Cp measurements is excellent for α-quartz (within 1% above 60°K) but is less satisfactory for vitreous silica because of inadequate knowledge of the distribution of frequencies below 500 cm—1.
