Calculation of the surface tension of liquid Gabased alloys

ABSTRACT
As known, Eyring and his collaborators have applied the
structure theory to the properties of binary liquid mixtures.
In this work, the Eyring model has been extended to calculate
the surface tension of liquid Ga–Bi, Ga–Sn and Ga–In binary
alloys. It was found that the addition of Sn, In and Bi into Ga
leads to significant decrease in the surface tension of the three
Ga-based alloy systems, especially for that of Ga–Bi alloys.
The calculated surface tension values of these alloys exhibit
negative deviation from the corresponding ideal mixing
isotherms. Moreover, a comparison between the calculated
results and corresponding literature data indicates a good
agreement.
