Abstract

The structure of molten K2SO4 has been investigated using the radial distribution function together with the correlation method based on X-ray scattering intensity data collected at ≈ 1150°C. The SO4 tetrahedron which exists in the crystalline state of K 2SO4 is shown to be preserved in the molten state. The most likely model for the short-range arrangement is that of four near-neighbour potassium atoms situated around the SO4 tetrahedron. One of the four potassium atoms practically occupies the corner-site and the others occupy the edge-sites. The nearest-neighbour K-O and K-S distance are r = 2.80 and 3.38 Å, respectively. The most likely model for the long-range arrangement is about thirteen K2SO4 units situated around one K 2SO4 unit with an average inter-unit distance of 7.0 Å.
