Abstract:
In this work the method of isotopic substitution in neutron diffraction is used to measure the partial structure factors of several binary systems. Molten sodium chloride at 820(5) °C is investigated and an improvement is made on the previously available data. The applicability of a simple model pair potential for the asymptotic decay of the pair correlation functions is discussed. The glass forming system zinc chloride is also investigated in both the molten phase at 332(5) °C and the glassy phase at 25(1) °C. The measured partial pair distribution functions show that the zinc atoms are fourfold coordinated in both the glass and the liquid and that the first sharp diffraction peak in the total structure factor is mainly due to the zinc-zinc correlations. A simple ionic model can account for several factors associated with the ultimate decay of the partial pair correlation functions.
