摘　　要：在钼丝炉内氩气保护下,利用固体电解质定氧探头测定了含镓1.87％～6.21％范围内Fe-Ca-O三元系平衡时的氧活度,通过处理得到镓在铁液中的标准溶解自由能等热力学参数与温度的关系。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.
