Abstract

The structure of K-Te liquid alloys at two different stoichiometric compositions was determined using the effective pair potentials based on the modified analytic embedded atom method (MAEAM) with the Variational Modified Hypernetted Chain (VMHNC) liquid state theory. The MAEAM potential functions are fitted to both solid and liquid state properties for only pure liquid metals. A new effective pair potential form based on the MAEAM has been proposed for the best possible structural properties of these alloys. The partial pair correlation functions for the K0.12Te0.88 at T = 723 K and equiatomic KTe at 770 K have been obtained. The results are in reasonably good agreement with experiments and MD results..
