The Seebeck coefficient, εT, of the thermocell Ag(T)/AgNO3 in NaNO3 − KNO3/Ag (T + ΔT) was measured as a function of silver nitrate concentration and temperature. Extrapolation of the results to unit mole fraction, N, of AgNO3 gave the value εT0 = − 277.5 − 0.136T °C (µV deg−1).For several mixed melts of AgNO3 and an alkali nitrate the function [Formula: see text] was calculated and shown to be linear in N. P was extrapolated to finite values for the pure alkali nitrates.

��� A relatively simple adiabatic calorimeter for use in the temperature range 50-350� was constructed and used to measure the specific heat of sodium nitrate from 150 to 300� and silver nitrate from 70 to 250�. Each salt undergoes a solid-solid and a solid-liquid transformation in these temperature ranges. The Cp values for sodium nitrate agreed within the calculated experimental error of �0.2% with those of Sokolov and Shmidt1 but the silver nitrate showed a large discrepancy with those of Janz and Kelly2 obtained by drop calorimetry for the 160-210� region, where thermal hysteresis may have occurred in the drop calorimetric technique. The heat of transformation for the solid-solid transition in silver nitrate at 159.4� was found to be 561�4 cal mole-1.

Electricity Transport

In a thermocell with silver electrodes the thermoelectric power ε at zero time of the molten systems (Ag + Rb)NO3 and (Ag + Cs) NO3 at various temperatures has been measured.These data, combined with previous measurements 1, allow to obtain information about the heat and electricity transport phenomena in the fused systems (AgNO3+alkali nitrates).
