“…The proposed procedure is similar to a method used elsewhere (Bale and Pelton, 1983d) for the treatment of metallurgical systems. The strategy has been applied with considerable success to alloys (Ashtakala et al, 1981a-c;Bale and Pelton, 1983a-c), oxides (Blander and Pelton, 1983; Pelton and Blander, 1984), molten salts (Bale and Pelton, 1982;Gabriel et al, 1985;Gabriel and Pelton, 1985;Hatem et al, 1982;Pelton et al, 1982;Sangster and Pelton, 1984), and other inorganic systems where there may be several phases. The objective is to provide one set of coefficients which enables the calculation of the various excess properties of mixing over the entire range of experimental conditions and permits reasonable extrapolations outside this region.…”
