Abstract: Based on principles of thermodynamics, it is derivd that in binary system the quasi-parabola regulation must be obeyedby the standard Gibbs free energy of formation of a compound.Extending to ternary system a quasi-paraboloid regulation also must be done. The stability of some intermetallic compounds in binary systems is decided

Key words: standard Gibbs free energy, binary phase diagram, intermetallic compound
