Calculation of the Specific Heats of Vitreous Silica and Components of Glasses as Functions of the Temperature

JSGT_1936_V20_T680_T694

Formulae are suggested for the average specific heats. These formulae have been established for vitreous silica, lime and alumina in view of the fact that the largest number of measurements have been carried out on these substances by different authors. The values calculated in this way correspond very accurately to most of the values observed at the temperatures between −273° and 2600°.
