New experimental results and improvment of the modelization of the (Ga,Mg) system

Abstract Differential enthalpic analysis gave solidus and liquidus lines of the diagram. MgGa melts congruently; Mg 2 Ga is a stoichiometric compound; MgGa 2 melts incongruently. The melting enthalpies of all the compounds were measured. A new numerical optimization of the thermodynamic properties was established using the NANCYUN program (Legendre polynomials), with all the known data. A consistent set of values in agreement with all the data (except one) is presented.
