Many of the Vargaftik values also appear in Ohse, R. W, Handbook of Thetmodynamic and Ttanspoti Ftopetiies of Alkali Metals, Blackwell Sci. Pubs., Oxford, 1985 (1020 pp.). This source contains superheat data. Saturation and superheat tables and a diagram to 30 bar, 1650 K are given by Reynolds, W. C., Thetmodynamic Fropetiies in S.I., Stanford Univ. publ., 1979 (173 pp.). For a Mollier diagram from 0.1 to 250 psia, 1300 to 2700°R, see Weatherford, W. D., J. C. Tyler, et al., WADD-TR-61-96, 1961. An extensive review of properties of the solid and the saturated liquid is given by Alcock, C. B., M. W. Chase, et al.,y. Fhys. Chem. Ref Data, 23, 3 (1994) 385-497.

The choice of die transporting reagent for a given material is made so diat die reaction is as complete as possible in one direction, in die uptake, and die reverse reaction in die opposite direction at die deposition site. This requires diat not only die choice of die reagent, but also die pressure and temperature ranges under which die reaction is most effectively, or quantitatively, performed, must be calculated (Alcock and Jeffes, 1967 1968). There will always be limitations placed on diis choice by die demands of die chemical ineruiess and temperature stability of die containing materials in which die reaction is canied out.

In liquid metal solutions Z is normally of the order of 10, and so this equation gives values of Ks(a+B) which are close to that predicted by the random solution equation. But if it is assumed that the solute atom, for example oxygen, has a significantly lower co-ordination number of metallic atoms than is found in the bulk of die alloy, dieii Z in the ratio of the activity coefficients of die solutes in the quasi-chemical equation above must be correspondingly decreased to the appropriate value. For example, Jacobs and Alcock (1972) showed that much of the experimental data for oxygen solutions in biiiaty liquid metal alloys could be accounted for by the assumption that die oxygen atom is four co-ordinated in diese solutions.
