由低温无水电解稀土夹杂物和固体电解质定氧活度测得Ni液中Ce_2O_3,CeS及Ce_2O_2S生成反应的平衡常数,由此可得: △G°_(Ce_2O_3)=-116240+315.8 T △G°_(Ces)=-570280+220.1 T △G°_(Ce_2O_2S)=-984850+238.5 T 由实验测得数据经热力学分析计算得到1600℃Ni液中a_O-a_S平衡图,为理论上预测夹杂物生成的先后次序及类型提供了依据。
The equilibrium constants of the reaction of Ce_2O_3, CeS and Ce_2O_2 in Ni solution were determined from the determination of the rare earth inclusions and the constant oxygen activity of solid electrolytes. From this we can get: △ G ° _ (Ce_2O_3) = - 116240 + 315.8 T △ Calculated from the experimental data obtained by the thermodynamic analysis of 1600 ℃ Ni liquid a_O-a_S equilibrium diagram for the theoretical prediction The order and type of inclusions generated provide the basis.
