Interdiffusion Coefficients

AbstractThe interdiffusion coefficients of the systems NaNO3+AgNO3 at 290 °C in the concentration range 0.25 ≦ x2 ≦ 1.0 (x2 mole fraction of the silver nitrate) and LiNO3 + AgNO3 at 260 °C in the total concentration range are determined by the diaphragm cell method. The dependence on time of the composition of the melt in the two compartments of the cell is followed up by emf-measurements. To that end we propose a new plotting method.

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.
