Computation of thermophysical properties of liquid metals and alloys on the basis of generalized version of hole theory

Highlights: • Modification of Frenkel's hole theory has been applied to liquid metals and alloys. • Liquid metals Na, K, Rb, Cs, Sn and Pb and four alloys K-Rb, Na-Cs, Sn-Pb and Na-K. • Various expressions for r_h,V_h, α, β_T, P_int, E_h, ∆E_V, ced, α_vdw and u were derived. • Interaction study of alkali metal alloys with the help of hole theory. • The calculated and experimental values show excellent. A generalized version of hole theory, recently developed as a modification of Frenkel's hole theory has been applied successfully, for the first time, to six pure liquid metals (K, Rb, Na, Cs, Pb and Sn) and four liquid metal alloys (K-Rb, Na-Cs, Sn-Pb and Na-K) at different temperatures. Various expressions for r_h,V_h, α, β_T, P_int, E_h, ΔE_V, ced, α_vdw and u were derived for the pure liquid metals and alloys. The calculated and experimental values show excellent agreement demonstrating the success of the theory to the pure liquid metals and alloys.
