The heat capacity of ultra-pure glasses of the (GeTe3. 76) ₁₀₀ - ₗ (AgI) x system is studied via differential scanning calorimetry in the 330–480 K range of temperatures at x = 10–50 mol %. Hydrostatic weighing shows the density of samples rises from 5. 475 to 5. 693 ± 0. 005 g/cm3 as the content of silver iodide grows. Results from a dilatometric study are used to determine the coefficient of thermal linear expansion in the 295 to 385 K range of temperatures. Consistent standard caloric and volumetric functions are calculated in the 0 to 450 K range of temperatures. A way of predicting these functions for intermediate unexplored glass compositions based on parametric similarity is proposed within the context of the theory.
