MICROSCOPIC STRUCTURE OF THE ALKALI-METAL ALKALI-HALIDE SOLUTIONS IN THE METALLIC REGIME - A NEUTRON-SCATTERING INVESTIGATION

The partial structure factors have been measured for two compositions (x = 0-8; x = 0-6) in the metallic regime of the solutions KxKCl)1-x, The potassium-potassium partials are compared with the pure potassium structure factor measured at 700°C. Ionic-like characteristics are obtained for the partials, even for x = 0-8. The number of potassium atoms surrounding chlorine is about four, suggesting rather open structures. Details are given on the data analysis of this difficult experiment. © 1990 Taylor & Francis Ltd.
