抄録

The heat capacities, C_p, of the alkali metal nitrates, MNO₃ (M= Li, Na, K, Rb, and Cs), in the solid and liquid states have been measured between 50 and 450 °C by means of adiabatic calorimetry. We have measured with a fair degree of accuracy the C_p values for the MNO₃ systems, because the existing data on NaNO₃ and KNO₃ above 250 °C are quite scanty. Some empirical rules, some of which may extend to other salts, have been obtained from the results on C_p for the five alkali nitrates in the solid and liquid states. For the molten MNO₃, the heat capacities at a constant volume, C_V, were obtained from the thermodynamical relationship between C_V and C_p, using the experimental values of C_p; the C_V values have been interpreted in terms of the interionic and intraionic portions.
