Abstract
The critical temperature of a gallium mercury mixture is increased by the addition of indium from 204°c to 211 °C. This maximal critical temperature is attained at the mole fraction indium x1, = 0.1. Six four-phase equilibria have been found.
The ternary liquid alloy is described by an Ising model. A hierarchy of three successively better mathematical approximations forthe entropy function: point, pair and tetrahedron approximation, is briefly delineated, comparing the calculated conodes with the experimentally determined ones it is found that the agreement between the ternary miscibility gap calculated in the tetrahedron approximation and the experimentally determined miscibility gap is quantitative.
