本文研究了在1550—1650℃Fe-V-Ce溶液体系的热力学性质。溶液中微量O,S与Ce建立平衡。已求得Ce与O,S反应的平衡常数。Ce_2O_2S的标准生成自由能及Ce与V的活度相互作用系数与温度的关系。
Reaction of Ce with S and O in liquid Fe-V-Ce solution has beenstudied in the temperature range of 1550 to 1670℃. The temperature dependences ofthe equilibrium constant of reaction Ce_2O_2S=2(Ce)+2(O)+(S) and the starndard freeenergy of formation of Ce_2O_2S have been obtained. The temperature dependences ofthe interaction coefficients e_V~(Ce) and e_(Ce)~V. have also been determined.
