“…[2] was used to calculate the surface tension of alkali, alkaline, and main group metals at the melting point. A comparison with the reported experimental values (Li, [34,35] Na, [34,35] K, [34,35] Rb, [36] Cs, [36] Al, [5,37,38] Ga, [14,39] In, [39][40][41][42] Pb, [42,43] Bi, [42][43][44][45] Tl, [46] Sn, [47][48][49] and alkaline earth metals [50][51][52] ) reveals a good agreement (Table I). Also, a comparison with the theoretical and experimental data reported by Lu and Jiang [46] and Egry et al [53] is reasonable.…”

An improved theoretical method for calculating the surface tension of liquid metals is proposed. A recently derived equation that allows an accurate estimate of surface tension to be made for the large number of elements, based on statistical thermodynamics, is used for a means of calculating reliable values for the surface tension of pure liquid alkali, alkaline earth, and main group metals at the melting point, In order to increase the validity of the model, the surface tension of liquid lithium was calculated in the temperature range 454 K to 1300 K (181°C to 1027°C), where the calculated surface tension values follow a straight line behavior given by c = 441 -0.15 (T-Tm) (mJ m À2 ). The calculated surface excess entropy of liquid Li (-dc/dT) was found to be 0.15 mJ m À2 K À1 , which agrees well with the reported experimental value (0.147 mJ/m 2 K). Moreover, the relations of the calculated surface tension of alkali metals to atomic radius, heat of fusion, and specific heat capacity are described. The results are in excellent agreement with the existing experimental data.

“…We have calculated the temperature of the transition of the aluminum liquid phase from "quasicrystal" to "quasigas" structure using the temperature dependence of aluminum viscosity (2) given in [5] (1), the temperature T was determined with the value being equal to 1. The calculations showed that the destruction of short-range order clusters in the liquid aluminum starts at T dest.clust 1606 K.…”

Abstract. The paper covers the evolution of the liquid phase formed under heating metal conductors by a pulse of current with the density of 10 6 ÷10 8 / m 2 . Following the theoretical assessment and experimental data, it was shown that the two-phase state (condensed phase -gas) during the early expansion of products of electric explosion of wires can be caused by the development of density fluctuations in the liquid phase of the metal. The density fluctuation formation is caused by the destruction of liquid phase clusters of short-range order. The study demonstrated the absence of the complete transition of the semiconductor matter into gas after the injection of energy exceeding the energy of sublimation s .
