应用定氧探头直接测定液态FexO的标准生成自由能

Measurement of Gibbs Energy of Liquid FexO by Disposable Oxygen Probe

    摘要
  • 摘要: 应用固体电解质定氧探头在1641~1733K的温度范围内,测定了液态FexO的标准生成自由能,并进行了误差分析,得到了以下结果:
    ⊿G°FexO=-222700+40.51T±800,J/mol
    该结果与多篇文献上所报道的⊿G°FexO与温度的关系式符合良好。

     

    Abstract: In this paper, the standard Gibbs energy of formation of liquid FexO was determined by using the oxygen probe with solid electrolyte and the error analysis of the method was done. The formula for measuring △G° of FexO was introduced, which is in good agreement with interature data.
