Measurement of Gibbs Energy of Liquid FexO by Disposable Oxygen Probe
-
摘要: 應用固體電解質定氧探頭在1641~1733K的溫度范圍內,測定了液態FexO的標準生成自由能,并進行了誤差分析,得到了以下結果:
⊿G°FexO=-222700+40.51T±800,J/mol
該結果與多篇文獻上所報道的⊿G°FexO與溫度的關系式符合良好。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.
