EQUILIBRIUM DETERMINATION OF Fe-Ga-O SYSTEM

Under Ar Protection in molybdenum-wound furnace oxygen activity at Fe-Ga-C ternary system equilibrium,with Ga content ranging from 1.87% to 6.21%,was determined by the solid electrolyte oxygen probe.The relation between the temperature and thermodvnamic parameters such as standard free energy etc.,of Ga dissolved in the molten iron is obtained.
